machineEpsilon top-level property

double machineEpsilon

Actual double precision machine epsilon, the smallest number that can be subtracted from 1, yielding a results different than 1.

This is also known as unit roundoff error. According to the definition of Prof. Demmel. On a standard machine this is equivalent to doublePrecision.

Implementation

final double machineEpsilon = _measureMachineEpsilon();
