	  		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.

		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.
