Input Parameters
| Name | Type | Description | 
|---|---|---|
| n | const MKL_INT | Specifies the number of elements to be calculated. | 
| a, b | const _Float16* for vhRemainder const float* for vsRemainder const _Float16* for vmhRemainder const float* for vmsRemainder const double* for vdRemainder const double* for vmdRemainder | Pointers to arrays containing the input vectors a and b. | 
| inca, incb, incy | const MKL_INT | Specifies increments for the elements of a, b, and y. | 
| mode | const MKL_INT64 | Overrides the global VM mode setting for this function call. See vmlSetMode for possible values and their description. | 
Output Parameters
| Name | Type | Description | 
|---|---|---|
| y | _Float16* for vhRemainder float* for vsRemainder _Float16* for vmhRemainder float* for vmsRemainder double* for vdRemainder double* for vmdRemainder | Pointer to an array containing the output vector y. | 
Description
Computes the remainder of each element of vector a, with respect to the corresponding elements of vector b: compute the values of n such that
n = ai - n*bi
where n is the integer nearest to the exact value of ai/bi. If two integers are equally close to ai/bi, n is the even one. If n is zero, it has the same sign as ai.
| Argument 1 | Argument 2 | Result | VM Error Status | Exception | 
|---|---|---|---|---|
| x not NAN | ±0 | NAN | VML_STATUS_DOM | INVALID | 
| ±∞ | y not NAN | NAN | INVALID | |
| ±0 | y≠ 0, not NAN | ±0 | ||
| x finite | ±∞ | x | UNDERFLOW if x is subnormal | |
| NAN | y | NAN | ||
| x | NAN | NAN | 
If element i in the result of v?Remainder is 0, its sign is that of ai.
