Summary

Calculates the Machine Epsilon value for the current precision.

Pascal

 procedure CalcMachineEps;

Description

This procedure calculates the Machine Epsilon value for the current precision and stores it in the variable Epsilon. Nontheless Epsilon is not used for any calculations. Per definition, all JCL functions which need a specific epsilon use the PrecisionTolerance variable instead. Therefore you need to call either SetPrecisionTolerance or SetPrecisionToleranceToEpsilon.
