v?Remainder

Performs element by element computation of the remainder function on the elements of vector a and the corresponding elements of vector b.

Syntax

vsRemainder (n, a, b, y);

vsRemainderI(n, a, inca, b, incb, y, incy);

vmsRemainder (n, a, b, y, mode);

vmsRemainderI(n, a, inca, b, incb, y, incy, mode);

vdRemainder (n, a, b, y);

vdRemainderI(n, a, inca, b, incb, y, incy);

vmdRemainder (n, a, b, y, mode);

vmdRemainderI(n, a, inca, b, incb, y, incy, mode);

Input Parameters

Name	Type	Description
`n`	const MKL_INT	Specifies the number of elements to be calculated.
`a, b`	const float* for vsRemainder 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`	float* for vsRemainder float* for vmsRemainder double* for vdRemainder double* for vmdRemainder	Pointer to an array containing the output vector `y`.

Description

y

float* for vsRemainder

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 = a_i - n*b_i

where n is the integer nearest to the exact value of a_i/b_i. If two integers are equally close to a_i/b_i, n is the even one. If n is zero, it has the same sign as a_i.

Special values for Real Function v?Remainder(x, y)
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

NOTE:

If element i in the result of v?Remainder is 0, its sign is that of a_i.
