exp (Pixel Shader)
Provides full precision exponential 2x.
Syntax
where
- dst is the destination register.
- src is a source register. Source register requires explicit use of replicate swizzle, that is, exactly one of the .x, .y, .z, .w swizzle components (or the .r, .g, .b, .a equivalents) must be specified.

The following code fragment shows the operations performed:
dest.x = dest.y = dest.z = dest.w = (float)pow(2, src0.w);
