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).
