Converting Between Fixed-Point and Floating-Point Values
The Mathematical and Logical Utilities provide four functions that allow you to convert between fixed-point and floating-point values represented using SANE's Extended floating-point data type. The Fix2X function and the X2Fix function convert between Fixed and Extended numbers. The Frac2X and X2Frac functions convert between Fract and Extended numbers. See Apple Numerics Manual for information about numeric data types supported by SANE.
