Summary

Epsilon and related variables hold the calculated machine Epsilon.

Pascal

 EpsSingle: Single;
EpsDouble: Double;
EpsExtended: Extended;
Epsilon: Float;
ThreeEpsSingle: Single;
ThreeEpsDouble: Double;
ThreeEpsExtended: Extended;
ThreeEpsilon: Float;

Description

Epsilon holds the calculated machine Epsilon. If no Epsilon has been calaculated by the CalcMachineEps procedure the value of Epsilon is undetermined.
Nontheless Epsilon is not used for any calculations. Per definition, all JCL functions which need a specific epsilon use the PrecisionTolerance variable instead. Therefor you need to call either SetPrecisionTolerance or SetPrecisionToleranceToEpsilon.
