import { atan2 } from "https://deno.land/x/denops_std@v6.4.0/function/mod.ts";
Return the arc tangent of {expr1} / {expr2}, measured in
radians, as a Float in the range [-pi, pi].
{expr1} and {expr2} must evaluate to a Float or a Number.
Returns 0.0 if {expr1} or {expr2} is not a Float or a
Number.
Examples:
:echo atan2(-1, 1)
-0.785398
:echo atan2(1, -1)
2.356194
Can also be used as a method:
Compute()->atan2(1)
