1 2 {{alias}}( x ) 3 Computes the hyperbolic arccosine of a number. 4 5 The domain of `x` is restricted to `[1,+infinity)`. If `x < 1`, the function 6 will return `NaN`. 7 8 Parameters 9 ---------- 10 x: number 11 Input value. 12 13 Returns 14 ------- 15 out: number 16 Hyperbolic arccosine (in radians). 17 18 Examples 19 -------- 20 > var v = {{alias}}( 1.0 ) 21 0.0 22 > v = {{alias}}( 2.0 ) 23 ~1.317 24 > v = {{alias}}( NaN ) 25 NaN 26 27 // The function overflows for large `x`: 28 > v = {{alias}}( 1.0e308 ) 29 Infinity 30 31 See Also 32 -------- 33
