NAME

       isinf - Test for infinity value.

       int isinf(float );

       intn isinf(floatn );

       int isinf(double );

       longn isinf(doublen );

       int isinf (half)      // if half
       extension enabled

       shortn isinf (halfn)      // if half
       extension enabled

DESCRIPTION

       Test for infinity value (positive or negative).

NOTES

       If an implementation extends this specification to support IEEE-754
       flags or exceptions, then all built-in relational functions shall
       proceed without raising the invalid floating-point exception when one
       or more of the operands are NaNs.

       The built-in relational functions are extended with cl_khr_fp16(3clc)
       to include appropriate versions of functions that take half, and
       half{2|3|4|8|16} as arguments and return values.

       The function returns a 0 if the specified relation is false and a 1 if
       the specified relation is true for scalar argument types. These
       functions shall return a 0 if the specified relation is false and a - 1
       (i.e. all bits set) if the specified relation is true for vector
       argument types.
