Rust - Arithmetic Operators


Advertisements

Assume the values in variables a and b are 10 and 5 respectively.

Sr.No Operator Description Example
1 +(Addition) returns the sum of the operands a+b is 15
2 -(Subtraction) returns the difference of the values a-b is 5
3 * (Multiplication) returns the product of the values a*b is 50
4 / (Division) performs division operation and returns the quotient a / b is 2
5 % (Modulus) performs division operation and returns the remainder a % b is 0

NOTE − The ++ and -- operators are not supported in Rust.

Illustration

fn main() {
   let num1 = 10 ;
   let num2 = 2;
   let mut res:i32;

   res = num1 + num2;
   println!("Sum: {} ",res);

   res = num1 - num2;
   println!("Difference: {} ",res) ;

   res = num1*num2 ;
   println!("Product: {} ",res) ;

   res = num1/num2 ;
   println!("Quotient: {} ",res);

   res = num1%num2 ;
   println!("Remainder: {} ",res);
}

Output

Sum: 12
Difference: 8
Product: 20
Quotient: 5
Remainder: 0
