`put` allocates uninitialized Buffers when non-round numbers are passed in input

I would like to report an uninitialized Buffer allocation issue in `put`. It allows to extract sensitive data from uninitialized memory by passing in non-round numbers, in setups where typed user input can be passed (e.g. from JSON).

var Put = require('put');
var buf = Put().pad(0.99).pad(0.99).pad(0.99).pad(0.99).pad(0.99).buffer();
console.log(buf);
