## Description

The `remquo` function computes the value `r` such that `r` = `x` - `k`*`y`, where `k` is the integer nearest the exact value of `x`/`y`. If there are two integers closest to `x`/`y`, `k` 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`.

General information about built-in math functions: The built-in math functions are categorized into the following:

• A list of built-in functions that have scalar or vector argument versions, and,

• A list of built-in functions that only take scalar float arguments.

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.

The built-in math functions take scalar or vector arguments. For any specific use of these function, the actual type has to be the same for all arguments and the return type unless otherwise specified.

The generic type name `gentype` is used to indicate that the function can take `float`, `float2`, `float3`, `float4`, `float8`, `float16`, `double`, `double2`, `double3`, `double4`, `double8`, or `double16` as the type for the arguments.

If extended with `cl_khr_fp16`, generic type name `gentype` may indicate `half` and `half{2|3|4|8|16}` as arguments and return values.

The generic type name `gentypef` is used to indicate that the function can take `float`, `float2`, `float3`, `float4`, `float8`, or `float16` as the type for the arguments.

The generic type name `gentyped` is used to indicate that the function can take `double`, `double2`, `double3`, `double4`, `double8`, or `double16` as the type for the arguments.
