Constant Value:
implementation-dependent.

Description:
The value of each of the constants short-float-epsilon, single-float-epsilon, double-float-epsilon, and long-float-epsilon is the smallest positive float of the given format, such that the following expression is true when evaluated:

(not (= (float 1 epsilon) (+ (float 1 epsilon) epsilon)))

The value of each of the constants short-float-negative-epsilon, single-float-negative-epsilon, double-float-negative-epsilon, and long-float-negative-epsilon is the smallest positive float of the given format, such that the following expression is true when evaluated:
