Predict the output of following program:
Can % be used with floating point numbers in C++?
#include <iostream> int main() { float f = 9.9f, m = 3.3f; float c = f % m; // LINE 5 std::cout << c; return 0; } |
The above program fails in compilation and compiler report the following error in line 5:
Output:
invalid operands of types 'float' and 'float' to binary 'operator%'
% operator cannot be used with floating point numbers in C & C++.
What about Java and C#?
This behavior is different in Java & C#. % operator can be used on floating point numbers in these languages.
Consider following example of Java program:
class Test { public static void main(String args[]) { float f = 9.9f, m = 3.3f; float c = f % m; System.out.println(c); } } |
Output:
3.2999997
Same way try this C# program. It works fine:
using System; class Test { public static void Main() { float f = 9.9f, m = 3.3f; float c = f % m; Console.WriteLine(c); } } |
Output:
3.3
