exp - vs

Provides full precision exponential 2x.

Syntax

exp dst, src

 

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. See Source Register Swizzling.

This instruction provides at least 21 bits of precision.

The following code fragment shows the operations performed:



dest.x = dest.y = dest.z = dest.w = (float)pow(2, src.replicateSwizzleComponent);
