java - How to check if number is a decimal?

Question

I create android app for dividing numbers.

int a,b;

int result = a/b;

if (result==decimal){

Log.v ("result","your result number is decimal")

} else {

Log.v ("result","your result number is not decimal")

}

How can I check if result is a decimal?

Answer 1

Use the modulus operator to check if there is a remainder.

if(a % b != 0) Log.v("result", "The result is a decimal");
else Log.v("result", "The result is an integer");
