Export assignment rempio2

• rempio2(x: number, y: Collection): number

• Computes x - nπ/2 = r.

  Notes

  • The function returns n and stores the remainder r as the two numbers y[0] and y[1], such that y[0] + y[1] = r.
  • For input values larger than 2^20 * π/2 in magnitude, the function only returns the last three binary digits of n and not the full result.

  Parameters

  • x: number

    input value

  • y: Collection

    remainder elements

  Returns number

  factor of π/2

  Example

  var y = [ 0.0, 0.0 ];
  var n = rempio2( 128.0, y );
  // returns 81
  
  var y1 = y[ 0 ];
  // returns ~0.765
  
  var y2 = y[ 1 ];
  // returns ~3.618e-17

  Example

  var y = [ 0.0, 0.0 ];
  var n = rempio2( NaN, y );
  // returns 0
  
  var y1 = y[ 0 ];
  // returns NaN
  
  var y2 = y[ 1 ];
  // returns NaN
