# SIN

Elemental Intrinsic Function (Generic): Produces the sine of an argument.

result = SIN (x)

x | (Input) Must be of type real or complex. It must be in radians and is treated as modulo 2*pi.

## Results

The result type and kind are the same as x.

If x is of type real, the result is a value in radians.

If x is of type complex, the real part of the result is a value in radians.

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)
1The setting of compiler options specifying real size can affect CSIN. 2This function can also be specified as ZSIN.

## Example

SIN (2.0) has the value 0.9092974.

SIN (0.8) has the value 0.7173561.
