6.2.3 Numerical comparison

Function: = z1 z2 z3 ...

[R5RS] If all the numbers z are equal, returns #t.

(= 2 2) => #t (= 2 3) => #f (= 2 2.0) => #t (= 2 2.0 2.0+0i) => #t

Function: < x1 x2 x3 ...

Function: <= x1 x2 x3 ...

Function: > x1 x2 x3 ...

Function: >= x1 x2 x3 ...

[R5RS] Returns #t If all the real numbers x are monotonically increasing, monotonically nondecreasing, monotonically decreasing, or monotonically nonincreasing, respectively.

Function: max x1 x2 ...

Function: min x1 x2 ...

[R5RS] Returns a maximum or minimum number in the given real numbers, respectively.

Function: min&max x1 x2 ...

Returns a maximum and minimum number in the given real numbers.
