var PI = require("../lib");

// Two decimals
console.log(PI(3));
console.log(PI(16));

// 100 decimals
console.log(PI(100));

var PI = require("../lib");

// Two decimals
console.log("3." + PI(3));
console.log("3." + PI(16));

// 100 decimals
console.log("3." + PI(1000));

Prepend "3." since the function returns the decimals.
