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.

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.
\(Sinh(CONJ(z))=CONJ(Sinh(z))\)
\(Sinh(-z)=-Sinh(z)\) .
