-### Infinity
+### False
 
-Infinity can be [treated as a number][infinity] in mathematics. Here, it's a number - primarily because 99% of use cases do not require checking for it, but doing so [makes our function 20-35% slower](./benchmark/code/infinity.js) in common use cases.
+See the [tests](./test.js) for more examples.
 
-If you want `Infinity` to be `false`, just do:
-
 ```js
-var isNumber = require('is-number');
-
-function isNum(val) {
-  return isNumber(val) && isFinite(val);
-}
+isNumber('foo')             //=> 'false'
+isNumber([1])               //=> 'false'
+isNumber([])                //=> 'false'
+isNumber(function () {})    //=> 'false'
+isNumber(Infinity)          //=> 'false'
+isNumber(NaN)               //=> 'false'
+isNumber(new Array('abc'))  //=> 'false'
+isNumber(new Array(2))      //=> 'false'
+isNumber(new Buffer('abc')) //=> 'false'
+isNumber(null)              //=> 'false'
+isNumber(undefined)         //=> 'false'
