gml_TFraction Class Reference #include <gml_Fraction.h> Collaboration diagram for gml_TFraction: [legend]List of all members. Detailed Description Fast integer representation of a floating-point number between 0 and 1. Provides a Merge() method for fast blending of two integers (e.g. for alpha-compositing purposes). Public Member Functions   gml_TFraction (Float32 fraction)   Build a gml_TFraction from the IEEE 32-bit float fraction.   gml_TFraction (UInt32 numerator, UInt8 exponent)   Build a gml_TFraction as numerator / 2 ** exponent.   gml_TFraction ()   Build the fraction representing 1. UInt32  Merge (const UInt32 a, const UInt32 b) const   Return a*f + b*(1-f) using only integer arithmetics. UInt32  Numerator () const   Return the numerator. UInt8  Exponent () const   Return the exponent. Float32  Value () const   Return the floating-point value corresponding to this fraction. Protected Attributes UInt8  fExponent   the opposite of the fraction's power-of-two exponent UInt32  fNumerator1   the fraction's numerator UInt32  fNumerator2   the numerator of the fraction's complement to 1 The documentation for this class was generated from the following file: math/gml_Fraction.h Generated on Tue Jun 12 14:03:28 2007 for gml by Doxygen 1.5.2.
