I want to use the javascript library

seedrandom.js

in a TypeScript project yet can't figure out how to write a type definition for this lib which extends the standard javascript Math library with an additional method:

Just add to the Math interface

interface Math {
    seedrandom(seed?: string);
}

Math.seedrandom();
