SetFPCompareAccuracy
Sets floating point compare accuracy by specifying the tolerance value to be used when floating point values are compared.
Two floating point values will be considered equal if "abs(Value1 – Value2) <= ε", where ε is the tolerance value.
By default, the tolerance value is 2.2204460492503131e-012.
Usage
SetFPCompareAccuracy(Accuracy)
Parameters
Accuracy - an FPC constant or a numerical expression specifying a tolerance value as follows:

5 | 0.00 |
Example
Set floating point compare accuracy to High:
SetFPCompareAccuracy(3);
Set floating point compare accuracy to High:
SetFPCompareAccuracy(fpcHighAccuracy);
