import { fn } from "https://deno.land/x/ddc_vim@v4.0.2/deps.ts";
const { rand } = fn;
Return a pseudo-random Number generated with an xoshiro128**
algorithm using seed {expr}. The returned number is 32 bits,
also on 64 bits systems, for consistency.
{expr} can be initialized by srand() and will be updated by
rand(). If {expr} is omitted, an internal seed value is used
and updated.
Returns -1 if {expr} is invalid.
Examples:
:echo rand()
:let seed = srand()
:echo rand(seed)
:echo rand(seed) % 16 " random number 0 - 15
Parameters
