Program For Addition Of Two Numbers In Lisp

  • Run a Program: Any list in Lisp is a program ready to run. In Lisp, this is written as follows. The arguments are the string and the two numbers. Google federated wiki and read around. You will find this wiki's missing pages. I had hoped that a distributed community would form that would carry forward and improve the original wiki beyond my lifetime, maybe forever. In the original LISP there were two fundamental data.
  • I'm implementing the calculator program using concurrent lisp. B)) (print 'ADDITION in binary. Lisp') Enter two numbers in binary.

Wiki has endured a number of abuses mostly protected by the goodwill of an obscure community for whom I have tremendous respect: wiki's authors.

(defun sum-n-numbers(n)(if(=n 1) 1 (+N(sum-n-numbers(-n 1))))) Edit 2: (defun sum-n-numbers(n) (if(=n 1) 1 (+N(sum-n-numbers(-n 1)) ) ) ) The above code runs but when I type (SUM-N-NUMBERS 1 3 2) for the output,it does not work and I get errors. I know this simple code can also be executed by the inbuild lisp function (+ 1 3 2) that automatically calculates the sum of the numbers,but I have an exam question where it is asked to calculate the sum of n numbers using the defun function.

Edit 1: This is the error that I am getting: Error: Call ((LAMBDA (#:N) (DECLARE (SPECIAL:SOURCE #) (LAMBDA-NAME SUM-N-NUMBERS)) (BLOCK #:SUM-N-NUMBERS (IF # 1 #))) 1 3 2) has the wrong number of arguments. 1 (abort) Return to level 1. 2 Return to debug level 1. 3 Return to level 0.

4 Return to top loop level 0. To get exactly what you want: (defun sum-n-numbers (&rest nums) (if (null nums) 0 (+ (car nums) (apply #'my-sum (cdr nums))))) This will take an arbitrary number of arguments and recursively compute their sum. For instance: (sum-n-numbers 1 2 3) = 6 Using iteration, not recursion: (defun sum-n-numbers (&rest nums) (loop for num in nums summing num)) From the user's point of view, these are the same, just a little bit different in how they work inside. And I've tested both of these to ensure they work.

Contents. Types of numbers The hierarchy of the number type is as follows:. number. real. rational. integer. fixnum.

bignum. ratio. float. short-float. single-float. double-float.

long-float. complex Fixnums and Bignums Fixnums are integers which are not too large and can be manipulated very efficiently.

Which numbers are considered fixnums is implementation-dependent, but all integers in -2 15,2 15-1 are guaranteed to be such. Bignums are integers which are not fixnums.

Program

Their size is limited by the amount of memory allocated for Lisp, and as such they can be really large. Operations on them are significantly slower than on fixnums. Of course, that doesn't make them less useful.

Ratios Ratios represent the ratio of two integers. They have the form numerator/ denominator.

The function / which performs division always produces ratios when its arguments are integers or ratios. For example (/ 1 2) will result in 1/2, not 0.5. Other arithmetic operations also work fine with ratios. Floats Float is short for, a datatype used to represent non-integer numbers in most programming languages. There are four kinds of floats in Common Lisp, which provide increasing precision (implementation-dependent). By default, implementations assume short floats, which have limited precision. To input a more precise float, other textual notations must be used, e.g., '1.0d0' for a double-float.

Complex Complex is a datatype for representing. The notation for complexes is #C( real imaginary). Real and imaginary parts are both either rational or floating-point.

The operations that can be performed on complexes include all arithmetic operations and also many other functions which can be extended to complex numbers (such as exponentiation and logarithm). Numeric Operations The following functions are defined for all kinds of numbers:. The arithmetical operations +, -,., / are quite obvious (note, though, that they can have more than two parameters). sin, cos, tan, acos, asin, atan provide trigonometric functions. The same, with h at the end (like asinh) provide corresponding hyperbolic functions. exp and expt perform exponentiation. Exp accepts one parameter and calculates e x, while expt accepts two parameters (base and power).

sqrt calculates the square root of a number. log calculates logarithms. If one parameter is supplied, the natural logarithm is calculated. If there are two parameters, the second parameter is used as the base. conjugate returns the of a number. For real numbers the result is the number itself. abs returns the absolute value (or magnitude) of a number.

phase returns the complex argument (angular component) of a number. signum returns a number with the same phase as its argument, but with unit magnitude. The following functions are defined for specific kinds of numbers:. gcd and lcm calculate and of several integers. isqrt returns the greatest integer less than or equal to the exact square root of a given natural number. cis calculates e iφ where φ is supplied in radians. Comparison of numbers The following functions can be used for comparison of numbers.

Each of these functions accepts any number of arguments. = returns t if all arguments are numbers of the same value and nil otherwise. Due to imprecise nature of floating-point numbers it is not advised to use = on them. /= returns t if all arguments are numbers of different value.

Two

Note that (/= a b c) is not always the same as (not (= a b c))., = check if their arguments are in the appropriate monotonous order. These functions can't be applied to complex numbers for obvious reasons. max and min return the largest and the least of their arguments, respectively.

Numeric type manipulation These functions are used to convert numbers from one type to another. floor, ceiling, truncate, round take two arguments: number and divisor and return quotient (an integer) and reminder= number- quotient. divisor. The method for choosing the quotient depends on the function.

Floor chooses the largest integer that is not greater than ratio= number/ divisor, ceiling chooses the smaller integer that is larger than ratio, truncate chooses the integer of the same sign as ratio with the largest absolute value that is less than absolute value of ratio, and round chooses an integer that is closest to ratio (if there are two such numbers, an even integer is chosen). Note: these functions return two values (see ).

ffloor, fceiling, ftruncate, fround are the same as above but the quotient is converted to the same float type as number. ( mod a b) returns the second value of ( floor a b). ( rem a b) returns the second value of ( truncate a b). float converts its first argument (a real) to a float. It may be useful to avoid slow operations with rational numbers (see example 1).

The second optional argument may be supplied, which must be float - it will be used as a prototype. The result would be of the same floating-point type as a prototype. Safeip pro full cracked mac. rational and rationalize convert a real number to rational. When this number is a float rational returns a rational number that is mathematically equivalent to float. Rationalize approximates the floating-point number.

The former function usually produces ratios with a huge denominator so it's not as useful as you may think. numerator and denominator return the corresponding parts of a rational number. complex creates a complex number from its real part and imaginary part.

Functions realpart and imagpart return real and imaginary part of a number. Predicates related to numbers Predicate returns a non-nil result if it's true and nil if it is false. zerop - the number is zero (there may be several zeros in Lisp - integer zero, real zero, complex zero, there may be negative zeros too). plusp, minusp - the real number is positive/negative.

evenp, oddp - the integer is odd/even. integerp - the number is integer (of the type integer - see type tree above). floatp - the number is float. rationalp - the number is rational. realp - the number is real. complexp - the number is complex.
