Return Value

Type: real

sine of x

Bugs

Results are undefined if |x| >= 2⁶⁴.

Examples

import std.math.constants : PI;
import std.stdio : writefln;

void someFunc()
{
  real x = 30.0;
  auto result = sin(x * (PI / 180)); // convert degrees to radians
  writefln("The sine of %s degrees is %s", x, result);
}
