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 <EPSILON> 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 <EPSILON> of the given format, such that the following expression is true when evaluated:

`(not (= (float 1 <EPSILON>) (- (float 1 <EPSILON>) <EPSILON>)))`

Examples: None.
