Question

How to find that a number is float or integer?

1.25 --> float  
1 --> integer  
0 --> integer  
0.25 --> float
<         


        

Answer 1

Here's what I use for integers:

Math.ceil(parseFloat(val)) === val

Short, nice :) Works all the time. This is what David Flanagan suggests if I'm not mistaken.
