%DECPOS (Get Number of Decimal Positions)

%DECPOS(numeric expression)

%DECPOS returns the number of decimal positions of the numeric variable or expression. The value returned is a constant, and so may participate in constant folding.

The numeric expression must not be a float variable or expression.
