Converting Among 32-Bit Numeric Types

The Operating System includes functions that allow you to convert among variables of type LongInt, Fixed, and Fract. The Long2Fix and Fix2Long functions convert between LongInt variables and Fixed variables. The Fix2Frac functions and Frac2Fix functions convert between Fixed and Fract variables. Ordinarily, there is no need to convert between LongInt and Fract variables, because Fract variables are used only to represent very small numbers. If you wish to do so, however, you can combine functions shown in this section.
