Export assignment kernelSin

• kernelSin(x: number, y: number): number

• Computes the sine of a number on [-π/4, π/4].

  Notes

  • For increased accuracy, the number for which the cosine should be evaluated can be supplied as a double-double number (i.e., a non-evaluated sum of two double-precision floating-point numbers x and y).
  • The two numbers must satisfy |y| < 0.5 * ulp( x ).

  Parameters

  • x: number

    input value (in radians, assumed to be bounded by ~pi/4 in magnitude)

  • y: number

    tail of x

  Returns number

  sine

  Example

  var v = kernelSin( 0.0, 0.0 );
  // returns ~0.0

  Example

  var v = kernelSin( 3.141592653589793/6.0, 0.0 );
  // returns ~0.5

  Example

  var v = kernelSin( 0.619, 9.279e-18 );
  // returns ~0.58

  Example

  var v = kernelSin( NaN, 0.0 );
  // returns NaN

  Example

  var v = kernelSin( 3.0, NaN );
  // returns NaN

  Example

  var v = kernelSin( NaN, NaN );
  // returns NaN
