SIN (The GNU Fortran Compiler)

### 8.261 `SIN` — Sine function ¶

Synopsis:

  `RESULT = SIN(X)`

Description:

  `SIN(X)` computes the sine of X.

Class:

  Elemental function

Arguments:

  X | The type shall be `REAL` or `COMPLEX`.

Return value:

  The return value has same type and kind as X.

Example:

      program test_sin
        real :: x = 0.0
        x = sin(x)
      end program test_sin

Specific names:

  Name | Argument | Return type | Standard
