f$Epsilon

Set or read numerical precision, e.g. for comparison operations on floating values. The condition

Number1 == Number2

is realized internally as

Number1 < Number2 + Epsilon AND Number1 > Number2 - Epsilon

The standard system default setting is 1E-8.

Syntax:	NewDelta = f$Epsilon( [Delta] )
	Argument	Type	Meaning
	Delta	Decimal	New numerical precision value (can be omitted) If the parameter is left out, the current setting is read.
Result:	Decimal	Numerical precision currently set
Example:	Read current setting: Delta = f$Epsilon( ) → Delta = 1E-8 Set new value: Delta = f$Epsilon( 1E-4 ) → Delta = 1E-4
