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.
Remarks
| Pixel shader versions | 1_1 | 1_2 | 1_3 | 1_4 | 2_0 | 2_x | 2_sw | 3_0 | 3_sw |
|---|---|---|---|---|---|---|---|---|---|
| exp | x | x | x | x | x |
The following code snippet shows the operations performed:
dest.x = dest.y = dest.z = dest.w = (float)pow(2, src.replicateSwizzleComponent);
