Export assignment sinpi

• sinpi(x: number): number

• Computes the value of sin(πx).

  Notes

  • The function computes sin(πx) more accurately than the obvious approach, especially for large x.

  Parameters

  • x: number

    input value

  Returns number

  function value

  Example

  var y = sinpi( 0.0 );
  // returns 0.0

  Example

  var y = sinpi( 0.5 );
  // returns 1.0

  Example

  var y = sinpi( 0.9 );
  // returns ~0.309

  Example

  var y = sinpi( NaN );
  // returns NaN
