Scalar

Instructions

Create the following functions, which each accept two parameters:

  • sum, which returns the sum between two values from 0 to 255
  • diff, which returns the difference between two values from -32768 to 32767
  • pro, which returns the product of the multiplication between two values from -128 to 127
  • quo, which returns the quotient of the division between two 32bit values
  • rem, which returns the remainder of the division between two 32bit values

You will need to figure out the exact data types for the parameters and the return values. There are some hints in the example.

pub fn sum(a: X , b: X) -> X {

}

pub fn diff(a: X, b: X) -> X {

}

pub fn pro(a: X, b: X) -> X {

}

pub fn quo(a: X, b: X) -> X {

}

pub fn rem(a: X, b: X) -> X {

}

Example

use scalar::*;

fn main() {
    // sum
    println!("sum : {}", sum(234, 2)); // 'sum : 236'
    println!("sum : {}", sum(1, 255)); // 'ERROR: attempt to add with overflow'
    // diff
    println!("diff : {}", diff(234, 2)); // 'diff : 232'
    println!("diff : {}", diff(-32768, 32766)); // 'ERROR: attempt to subtract with overflow'
    // product
    println!("pro : {}", pro(23, 2)); // 'pro : 46'
    println!("pro : {}", pro(-128, 2)); // 'ERROR: attempt to multiply with overflow'
    // quotient
    println!("quo : {}", quo(22.0, 2.0));// 'quo : 11'
    println!("quo : {}", quo(-128.23, 2.0));// 'quo : -64.115'
    // remainder
    println!("rem : {}", rem(22.0, 2.0));// 'rem : 0'
    println!("rem : {}", rem(-128.23, 2.0));// 'rem : -0.22999573'
}
