sack::math::fraction Namespace

Fraction namespace contains a PFRACTION type which is used to store integer fraction values. Provides for ration and proportion scaling. Can also represent fractions that contain a whole part and a fractional part (5 2/3 : five and two-thirds).

Functions

	Name	Description
	AddCoords
	AddFractions	Add one fraction to another.
	InverseScaleValue
	LogCoords	Log coordpair to logfile.
	MulFractions	NOT IMPLEMENTED
	ReduceFraction	Results in the integer part of the fraction. If the faction was 330/10 then the result would be 33.
	ScaleFraction	scales a fraction by a signed integer value.
	ScaleValue	Scales a 32 bit integer value by a fraction. The result is the scaled value result.
	sLogCoords	Unsafe log of a coordinate pair's value into a string. The string should be at least 69 characters long.
	sLogFraction	Log a fraction into a string.

Macros

Name	Description
FRACTION_API	Define the call type of the function.
FRACTION_PROC	Define the library linkage for a these functions.
SetFraction
SetFractionV	Sets the value of a FRACTION. This is passed as the whole number and the fraction.

Structs, Records, Enums

	Name	Description
	coordpair_tag	A coordinate pair is a 2 dimensional fraction expression. can be regarded as x, y or width,height. Each coordiante is a Fraction type.

	COORDPAIR	A coordinate pair is a 2 dimensional fraction expression. can be regarded as x, y or width,height. Each coordiante is a Fraction type.
	FRACTION	The faction type. Stores a fraction as integer numerator/denominator instead of a floating point scalar. Pointer to a FRACTION. The faction type. Stores a fraction as integer numerator/denominator instead of a floating point scalar.
