How to check if a number is an integer without using math function and without converting number into string or array
1) Use the === operator (strict equality) as below,
2) Check if the type is number and then check the remainder
if (data === parseInt(data, 10))
alert("data is integer")
else
alert("data is not an integer")
var data = 22;
if(typeof data === 'number'){
// yes it is numeric
if(data % 1 === 0){
// yes it's an integer.
}
}
