1 2 {{alias}}( x, y ) 3 Computes `x - nπ/2 = r`. 4 5 The function returns `n` and stores the remainder `r` as the two numbers 6 `y[0]` and `y[1]`, such that `y[0] + y[1] = r`. 7 8 For input values larger than `2^20 * π/2` in magnitude, the function only 9 returns the last three binary digits of `n` and not the full result. 10 11 Parameters 12 ---------- 13 x: number 14 Input value. 15 16 y: Array|TypedArray|Object 17 Remainder elements. 18 19 Returns 20 ------- 21 n: integer 22 Factor of `π/2`. 23 24 Examples 25 -------- 26 > var y = [ 0.0, 0.0 ]; 27 > var n = {{alias}}( 128.0, y ) 28 81 29 > var y1 = y[ 0 ] 30 ~0.765 31 > var y2 = y[ 1 ] 32 ~3.618e-17 33 34 35 See Also 36 -------- 37
