gentype
remquo
(
| gentype x, |
gentype y, | |
intn *quo) |
The remquo
function computes the value r
such
that r
= x
- n
*y
, where n
is the integer nearest the
exact value of x
/y
. If there are two integers closest
to x
/y
, n
shall be the even one. If r
is zero, it is
given the same sign as x
. This is the same value
that is returned by the remainder function.
remquo
also calculates the lower seven bits of the
integral quotient x
/y
, and gives that value the same
sign as x
/y
. It stores this signed value in the object
pointed to by quo
.
The vector versions of the math functions operate component-wise. The description is per-component.
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.
This built-in math function takes scalar or vector arguments. The generic type name gentype is used to indicate that the function can take float, float2, float4, float8, or float16 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 cl_khr_fp64, generic type name gentype may indicate double and double{2|4|8|16} as arguments and return values. If extended with cl_khr_fp16, generic type name gentype may indicate half and half{2|4|8|16} as arguments and return values.
