| <h2>Notes</h2> |
| <p> |
| If an implementation extends this specification to support IEEE-754 flags or |
| exceptions, then all built-in relational functions shall proceed without raising the |
| <code class="varname">invalid</code> floating-point exception when one or more of the operands |
| are NaNs. |
| </p> |
| <p> |
| The built-in relational functions are extended with |
| <a class="citerefentry" href="cl_khr_fp16.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_fp16</span></span></a> to |
| include versions that take <span class="type">half</span>, and |
| <span class="type">half{2|3|4|8|16}</span> as arguments. |
| </p> |
| <p> |
| The function returns a 0 if the specified relation is <code class="constant">false</code> and a 1 |
| if the specified relation is <code class="constant">true</code> for scalar argument types. These |
| functions shall return a 0 if the specified relation is <code class="constant">false</code> and a - |
| 1 (i.e. all bits set) if the specified relation is <code class="constant">true</code> for vector |
| argument types. |
| </p> |
| <p> |
| The function returns 0 if either argument is not a number (NaN). |
