Description 

 

leAbsoluteValue 

Calculates the absolute value of a signed integer. 

 

leArcsOverlapQuadrant 

Returns true if arc overlaps with quadrant 

 

leAtan 

Performs the inverse tangent operation 

 

leClampf 

Clamps a float between a min and max 

 

leClampi 

Clamps an integer between a min and max 

 

leDivideRounding 

Calculates integer division of num/denom with rounding based on LSB/2. 

 

leEllipsePoint 

Performs a cosine lookup to determine the points in an arc at specified radius and angle (polar > cartesian conversion) 

 

leGetXGivenYOnLine 

Projects a point onto another point given a y coordinate. 

 

leGetYGivenXOnLine 

Projects a point onto another point given a x coordinate. 

 

leLerp 

Performs a linear interpolation of an integer based on a percentage between two signed points. 

 

leMaxf 

Returns the larger of two floats. 

 

leMaxi 

Returns the larger of two integers. 

 

leMinf 

Returns the smaller of two floats. 

 

leMini 

Returns the smaller of two integers. 

 

leNormalizeAngle 

normalize an angle between 0 - 360 

 

lePercent 

Calculates the percentage of one number when applied to another. Integer based. Accuracy for higher numbers is not guaranteed.
The result is the decimal percentage multiplied by 100. 

 

lePercentOf 

Calculates the percentage of a number. Returns a whole number with no decimal component. 

 

lePercentOfDec 

Calculates the percentage of a number. Returns a whole number and the tenths digit decimal component. 

 

lePercentWholeRounded 

Calculates the percentage of one number when applied to another. Integer based. Accuracy for higher numbers is not guaranteed.
The difference between this and lePercent is that the decimal portion of the whole number is rounded off. 

 

lePolarToXY 

Performs a cosine lookup to determine the points in an arc at specified radius and angle (polar to Cartesian conversion) 

 

leScaleInteger 

Scales an integer from one number range of 0 -> n0 to another range 0 -> n1 based on percentages. 

 

leScaleIntegerSigned 

Scales a signed integer from one number range of 0 -> n0 to another range 0 -> n1 based on percentages. 

 

leSortPointsX 

Sorts two points on the X axis. 

 

leSortPointsY 

Sorts two points on the Y axis.
