Remarks

Decimal separator

The decimal separator for the real numbers is the one defined in the control panel of Windows.

Precision of the reals

If the parameter passed to the function is a real, the result is always an 8-byte real.

If the parameter passed to the function is a 4-byte real, the result will be considered as being an 8-byte real, which may result in additional decimal places when displaying the number. For example:

rValue is 4-byte real = -1.70
Trace(Abs(rValue)) // Displays 1.700000047684

To avoid this type of problem, we advise you to use reals (without specifying the size) or currencies.
