is it possible?

**koyboy** · 05-24-2008

Code:

if((first/second)!=int)

is it possible?? I want to get result is int or not??

because result can be float..

Code:

if((first&#37;second)!=0)

I think this is how it will be done. Keep in mind that 'first' and 'second' should be int for this.

Don't use my code if its a nuclear project you're doing though, because 70% of my code is wrong.

C is a strongly typed language. If you divide an int with an int, you will get an integer back and nothing else.
The result will never be a float UNLESS you divide an integer with a float in which case you WILL get a float back.
If you want to check if it can be represented in an integer (ie, no decimals), then you can try something like
first % (int)first == 0

I know it.. but result is false..Like this:
1)first and second value is random (Example first:15 second:10)
2)ask user first/second
3)if user enter 1 its correct in programming but it isnt correct in real math..

so I want to create first and second value which can be something that is divisible by one another..

I write like this and thats ok...

Code:

second = (rand()&#37;99)+1
do{
      	first = second * ((rand()%10)+1);
      }while(first>=100);

and if I ask first/second, result is exactly int in real and in programming and first%second=0

I see no problem with this..
first%second gives remainder, I think you know that?

So if first%second==0, that means the remainder is zero and quotient is an int. Same as what "real" math says.

Funny you should say that. I've actually written code that one place it runs is a nuclear facility.
Aparently when our system goes down, a loud siren can be heard for miles... according to one of our guys that was sent over there once.
I'm not kidding.

Are first & second defined as ints or as floats or doubles?

**ssharish2005** · 05-24-2008

@cpjust in think, they are all int, since they are generated by rand as per what Op says.
