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);

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

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

       genBType mix(genBType x, genBType 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 $x \times (1 - a) + y \times a$.

       The variants of mix where a is genBType select which vector each returned component comes
       from. For a component of a that is false, the corresponding component of x is returned.
       For a component of a that is true, the corresponding component of y is returned.
       Components of x and y that are not selected are allowed to be invalid floating-point
       values and will have no effect on the results.
