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.
