| This function returns a 0 if the specified relation is <emphasis>false</emphasis> and a 1 if the specified relation is <emphasis>true</emphasis> for scalar argument types. It returns a 0 if the specified relation is <emphasis>false</emphasis> and a -1 (i.e. all |
| bits set) if the specified relation is <emphasis>true</emphasis> for vector argument types. |
| </para> |
| <para> |
| This function can be used with built-in scalar or vector types as arguments and return a scalar vector integer result. The argument type igentype refers to signed integer vector types i.e. <type>char</type>, <type>char<replaceable>n</replaceable></type>, <type>short</type>, <type>short<replaceable>n</replaceable></type>, <type>int</type>, <type>int<replaceable>n</replaceable></type>, <type>long</type>, and <type>long<replaceable>n</replaceable></type>. |

| If extended with <citerefentry><refentrytitle>cl_khr_fp64</refentrytitle></citerefentry>, generic type name <type>gentype</type> may indicate <type>double</type> and <type>double{2|4|8|16}</type> as arguments and return values. If extended with <citerefentry><refentrytitle>cl_khr_fp16</refentrytitle></citerefentry>, generic type name <type>gentype</type> may indicate <type>half</type> and <type>half{2|4|8|16}</type> as arguments and return values. |
