Given the following problem (SICP Exercise 1.3): Define a procedure that takes three numbers as arguments and returns the sum of squares of the two largest. LISP Tutorial 2: Advanced Functional Programming in LISP. Fm Genie Scout 2011 Patch 11.3 Ansys Maxwell Student Version. there. The latter is equivalent to adding. If two arguments number and divisor are passed to the.
Common Lisp defines several kinds of numbers. The number data type includes various kinds of numbers supported by LISP. The number types supported by LISP are: • Integers • Ratios • Floating-point numbers • Complex numbers The following diagram shows the number hierarchy and various numeric data types available in LISP: Various Numeric Types in LISP The following table describes various number type data available in LISP: Data type Description fixnum This data type represents integers which are not too large and mostly in the range -215 to 215-1 (it is machine-dependent) bignum These are very large numbers with size limited by the amount of memory allocated for LISP, they are not fixnum numbers. Ratio Represents the ratio of two numbers in the numerator/denominator form. The / function always produce the result in ratios, when its arguments are integers. Float It represents non-integer numbers. There are four float data types with increasing precision.
Complex It represents complex numbers, which are denoted by #c. The real and imaginary parts could be both either rational or floating point numbers. Example Create a new source code file named main.lisp and type the following code in it. (write (/ 1 2)) (terpri) (write ( + (/ 1 2) (/ 3 4))) (terpri) (write ( + #c( 1 2) #c( 3 -4))) When you execute the code, it returns the following result: 1/2 5/4 #C(4 -2) Number Functions The following table describes some commonly used numeric functions: Function Description +, -, *, / Respective arithmetic operations sin, cos, tan, acos, asin, atan Respective trigonometric functions. Sinh, cosh, tanh, acosh, asinh, atanh Respective hyperbolic functions. Exp Exponentiation function. Calculates e x expt Exponentiation function, takes base and power both.
