Scheme Floor Function

Ceiling x this returns the smallest integer that is no smaller than x.

Scheme floor function.

Scheme provides a set of functions for rounding a real number up down or to the nearest integer. When called with two integer arguments min and max returns a random exact integer in the range min to max 1. In each case the number is provided by the given pseudo random number generator which defaults to the current one as produced by current pseudo random generator. Scheme s way of printing lists uses a shorthand which hides the final in the responses above we simply see the elements of a list enclosed in parentheses.

However you re not allowed to use the floor round ceiling and sgn function. Floor function in excel is very similar to the rounddown function as it rounds down the number to its significance for example if we have number as 10 and the significance is 3 the output would be 9 this function takes two arguments as an input one is a number while other is the significance value. They compute the usual transcendental functions. When called with zero arguments returns a random inexact number between 0 and 1 exclusive.

In addition to all this you are unable to use recursion cond lists or even helper functions. Scheme s numerical operations treat numbers as abstract data as independent of their representation as possible. The first argument of cons may be any scheme object and the second is a list. Use only beginner student documentation.

The value of cons x xs is a new list which contains x followed by the elements of xs.
