import { fn } from "https://deno.land/x/dpp_vim@v0.2.0/deps.ts";
const { asin } = fn;
Return the arc sine of {expr} measured in radians, as a Float
in the range of [-pi/2, pi/2].
{expr} must evaluate to a Float or a Number in the range
[-1, 1].
Returns "nan" if {expr} is outside the range [-1, 1]. Returns
0.0 if {expr} is not a Float or a Number.
Examples:
:echo asin(0.8)
0.927295
:echo asin(-0.5)
-0.523599
Can also be used as a method:
Compute()->asin()
