| The vector versions of the math functions operate |
| component-wise. The description is per-component. |
| </p> |
| <p> |
| The built-in math functions are not affected by the prevailing rounding mode in the calling |
| environment, and always return the same value as they would if called with the round to |
| nearest even rounding mode. |
| </p> |
| <p> |
| The built-in math functions take scalar or vector arguments. For any specific use of these |
| function, the actual type has to be the same for all arguments and the return type unless |
| otherwise specified. |
| </p> |
| <p> |
| The generic type name <span class="type">gentype</span> is used to indicate that the function can |
| take <span class="type">float</span>, <span class="type">float2</span>, <span class="type">float3</span>, <span class="type">float4</span>, |
| <span class="type">float8</span>, <span class="type">float16</span>, <span class="type">double</span>, <span class="type">double2</span>, |
