| <p> |
| <code class="function">rint</code> always rounds according to round to nearest even rounding mode even if the caller is in |
| some other rounding mode. |
| </p> |
| <p> |
| 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> |
| This built-in math function takes scalar or vector arguments. 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">float4</span>, <span class="type">float8</span>, or <span class="type">float16</span> as the type for the arguments. For any specific |
| use of these function, the actual type has to be the same for all arguments and the return type. |
| </p> |
| <p> |
| If extended with <a class="citerefentry" href="cl_khr_fp64.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_fp64</span></span></a>, generic type name <span class="type">gentype</span> may indicate <span class="type">double</span> and <span class="type">double{2|4|8|16}</span> as arguments and return values. If extended with <a class="citerefentry" href="cl_khr_fp16.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_fp16</span></span></a>, generic type name <span class="type">gentype</span> may indicate <span class="type">half</span> and <span class="type">half{2|4|8|16}</span> as arguments and return values. |
