Elemental Intrinsic Function (Generic): Produces the sine of x.
Syntax
result = SIN (x)
x
(Input) Must be of type real or complex. It must be in radians and is treated as modulo 2*pi.
If x is of type complex, its real part is regarded as a value in radians.
Results
The result type is the same as x.
| Specific Name | Argument Type | Result Type |
|---|---|---|
| SIN | REAL(4) | REAL(4) |
| DSIN | REAL(8) | REAL(8) |
| QSIN | REAL(16) | REAL(16) |
| CSIN 1 | COMPLEX(4) | COMPLEX(4) |
| CDSIN 2 | COMPLEX(8) | COMPLEX(8) |
| CQSIN | COMPLEX(16) | COMPLEX(16) |
| 1 The setting of compiler options specifying real size can affect CSIN. 2 This function can also be specified as ZSIN. |
