so I have 2 different variables, int a and double b
I tried to do
if ( a = b ) {
Condition
}
But that doesn't work, and I'm not sure if a==b is the same thing.
It's a program where I need to do stuff with 2 numbers, and need to find out if the result is an integer, then print it if it's an integer.
so since int's ignore decimals and doubles don't, i set them equal so unless b is a whole number, it won't equal.
Sorry I'm new to java, I can't figure out hwo to check if a number is an integer, and nothing too complex that we haven't learned, because this is an assignment for class.
Thanks!

The operators '=' (one equals sign) and '==' (two equals signs) are definitely different.
The first one assigns the value of the right hand side to the left hand side. The other
operator compares both operands for equality and returns true or false, depending
on the equality.
About your question: have a look at the Math.rint(double x) method; it returns
an integer value closest to its operand x, so if x == Math.rint(x) is true the value
x represents an integer value.
kind regards,

Actually, I just realized I need 2 methods for this assignment, I need the user to input 2 integers and it finds the least common denominator of the 2 digits and prints it.
I don't really want the actually code, but I don't really understand the whole concept of how to use 2 methods.
I originally planned on multiplying a input by a loop++; until it reaches a number input 2 can divide it so that it is an integer.
Any help? =]
Thanks~!
Any help?
Not from me because your description doesn't make sense to me at all.
kind regards,
Jos
