_Decimal32 sind32(_Decimal32 x);
_Decimal64 sind64(_Decimal64 x);
_Decimal128 sind128(_Decimal128 x);
_Decimal32 sin(_Decimal32 x); /* C++ only */
_Decimal64 sin(_Decimal64 x); /* C++ only */
_Decimal128 sin(_Decimal128 x); /* C++ only */
General description
Calculates the sine
of x, with x expressed
in radians.
Notes:
- To use IEEE decimal floating-point, the hardware must have the Decimal Floating-Point Facility installed.
- These functions work in IEEE decimal floating-point format. See "IEEE Decimal Floating-Point" for more information.
Returned value
If successful, the function returns the calculated value, expressed as a _Decimal32, _Decimal64, or _Decimal128.
If x is outside prescribed limits, the value is not calculated. Instead, the function returns 0 and sets errno to EDOM.
Example
