Name

mix — linearly interpolate between two values

Declaration

genType mix(genType x, genType y, genType a);

genType mix(genType x, genType y, float a);

genDType mix(genDType  x,
 genDType  y,
 genDType  a);

genDType mix(genDType x, genDType y, double a);

genType mix(genType x, genType y, genBType a);

genDType mix(genDType  x,
 genDType  y,
 genBType  a);

Parameters

x

Specify the start of the range in which to interpolate.

y

Specify the end of the range in which to interpolate.

a

Specify the value to use to interpolate between x and y.

Description

mix performs a linear interpolation between x and y using a to weight between them. The return value is computed as follows: x ( 1 a ) + y a .

For the variants of mix where a is genBType, elements for which a[i] is false, the result for that element is taken from x, and where a[i] is true, it will be taken from y.
