Parameters

pSrc	Pointer to the source vector.
pDst	Pointer to the destination vector.
len	Number of elements in the vectors.

Description

The function ippsSinh is declared in the ippvm.h file. This function computes the hyperbolic sine of each element of pSrc, and stores the result in the corresponding element of pDst.

For single precision data:

function flavors ippsSinh_32f_A11and ippsSinh_32cf_A11 guarantee 11 correctly rounded bits of significand, or at least 3 exact decimal digits;

function flavors ippsSinh_32f_A21 and ippsSinh_32fc_A21 guarantee 21 correctly rounded bits of significand, or 4 ulps, or about 6 exact decimal digits;

function flavors ippsSinh_32f_A24 and ippsSinh_32fc_A24 guarantee 24 correctly rounded bits of significand, including the implied bit, with the maximum guaranteed error within 1 ulp.

For double precision data:

function flavors ippsSinh_64f_A26 and ippsSinh_64fc_A26 guarantee 26 correctly rounded bits of significand, or 6.7E+7 ulps, or approximately 8 exact decimal digits;

function flavors ippsSinh_64f_A50 and ippsSinh_64fc_A50 guarantee 50 correctly rounded bits of significand, or 4 ulps, or approximately 15 exact decimal digits;

function flavors ippsSinh_64f_A53 and ippsSinh_64fc_A53 guarantee 53 correctly rounded bits of significand, including the implied bit, with the maximum guaranteed error within 1 ulp.

The computation is performed as follows:

pDst[n] = sinh(pSrc[n]), 0 ≤ n < len.

The example below shows how to use the function ippsSinh.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when pSrc or pDst pointer is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
IppStsOverflow	In real functions, indicates a warning that the function overflows, that is, at least one of elements of pSrc has the absolute value greater than Ln(FPMAX) + Ln(2), where FPMAX is the maximum representable floating-point number.

Using ippsSinh Function

IppStatus ippsSinh_32f_A21_sample(void)

const Ipp32f x[4] = {-2.483, -8.148, 3.544, -8.876};

Ipp32f      	y[4];

	IppStatus st = ippsSinh_32f_A21( x, y, 4 );

	printf(" ippsSinh_32f_A21:\n");

	printf(" x = %.3f %.3f %.3f %.3f \n", x[0], x[1], x[2], x[3]);

	printf(" y = %.3f %.3f %.3f %.3f \n", y[0], y[1], y[2], y[3]);

	return st;

Output results:

 ippsSinh_32f_A21:

 x = -2.483 -8.148 3.544 -8.876

 y = -5.945 -1727.412 17.290 -3577.970
