Check a value is float or int in jquery

Question

I have the following html field, for which i need to check whether the input value is float or int,

<p class="check_int_float" name="float_int" type="text"></p>


$(document).ready(function(){
   $('.check_int_float').focusout(function(){

       var value  = this.value
       if (value is float or value is int)
          {
           // do something
          }      
       else
          {
           alert('Value must be float or int');   
          }  

   });

});

So how to check whether a value is float or int in jquery.

I need to find/check both cases, whether it is a float, or int, because later if the value was float i will use it for some purpose and similarly for int.

Answer 1

use typeof to check the type, then value % 1 === 0 to identify the int as bellow,

if(typeof value === 'number'){
   if(value % 1 === 0){
      // int
   } else{
      // float
   }
} else{
   // not a number
}
