Floating-point Vector Classes

The floating-point vector classes,
F64vec2
,
F32vec4
, and
F32vec1
, provide an interface to SIMD operations. The class specifications are as follows:
F64vec2 A(double x, double y);
F32vec4 A(float z, float y, float x, float w);
F32vec1 B(float w);
The packed floating-point input values are represented with the right-most value lowest as shown in the following table.
