isNumber

isNumber is a super tiny module that provides a test to see if a value is a finite number.

By super tiny, I mean like a single line -- however, I tend to use this somewhat frequently, so module it is!

var isNumber = require("isnumber")
 
isNumber(13) // true
isNumber("1241.12") // true
isNumber(0xff) // true
 
isNumber(Infinity) // false
isNumber("cat") // false
isNumber({foo: "bar"}) // false
