Input Parameters

Name	Type	Description
n	const MKL_INT	Specifies the number of elements to be calculated.
a	const float* for vsSinh, vmsSinh const double* for vdSinh, vmdSinh const MKL_Complex8* for vcSinh, vmcSinh const MKL_Complex16* for vzSinh, vmzSinh	Pointer to an array that contains the input vector a.
inca, incy	const MKL_INT	Specifies increments for the elements of `a` and `y`.
mode	const MKL_INT64	Overrides global VM mode setting for this function call. See vmlSetMode for possible values and their description.

Precision Overflow Thresholds for Real v?Sinh Function
Data Type	Threshold Limitations on Input Parameters
single precision	`-Ln(FLT_MAX)-Ln2 <a[i] < Ln(FLT_MAX)+Ln2`
double precision	`-Ln(DBL_MAX)-Ln2 <a[i] < Ln(DBL_MAX)+Ln2`

Precision overflow thresholds for the complex v?Sinh function are beyond the scope of this document.

See Special Value Notations for the conventions used in the table below.

Special Values for Complex Function v?Sinh(z)

Notes:

raises the INVALID exception when the real or imaginary part of the argument is SNAN
raises the OVERFLOW exception and sets the VM Error Status to VML_STATUS_OVERFLOW in the case of overflow, that is, when RE(z), IM(z) are finite non-zero numbers, but the real or imaginary part of the exact result is so large that it does not meet the target precision.
Sinh(CONJ(z))=CONJ(Sinh(z))
Sinh(-z)=-Sinh(z).
