isnumber

A simple test to see if a value is a non-infinite number.

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
