### Instructions
4 years ago
Create the following **functions**, which each receives 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 values (32bit and you have to figure out the second part)
- `rem`, which returns the remainder of the division between two values (32bit and you have to figure out the second part)
You **must** complete the Expected functions parameters data type accordingly (Replace the Xs)!

### Expected functions (Incomplete, you must precise the Data Types)
```rust
4 years ago
pub fn sum(a: X , b: X) -> X {
}
4 years ago
pub fn diff(a: X, b: X) -> X {
}
4 years ago
pub fn pro(a: X, b: X) -> X {
}
4 years ago
pub fn quo(a: X, b: X) -> X {
}
4 years ago
pub fn rem(a: X, b: X) -> X {
}
```
### Usage :
#### Note that There is no output for this test for you to train to comment accordingly.
```rust
use scalar::*;
4 years ago
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'
}
```
