hash-int

Given an integer, deterministically computes a psuedorandom unsigned 32 bit integer. Based on Thomas Wang's 7-shift integer hash algorithm. For more discussion and experiments, see the following references:

* Thomas Wang's Original Homepage (now down): http://www.cris.com/~Ttwang/tech/inthash.htm
* Bob Jenkins' Write Up: http://burtleburtle.net/bob/hash/integer.html

Install

npm install hash-int

Example

``javascript
var hashInt = require("hash-int")

for(var i=-10; i<=10; ++i) {
console.log(hashInt(i))
}
`

$3


Given an integer x as a seed, computes a psuedorandom integer.

* x the seed value

Returns: A signed 32 bit integer representing the value of x`
