HexGa Number

Provide basic number functionality, like

• Some constant in trait : Zero One Half, MaxValue, MinValue, NaNValue,

• Some trait that regroup multiple operation :

  • Type of operations

    • BitArithmetic : For every type that support bit based operation (and &, or |, xor ^, not !, shift << / >>...).
    • UnitArithmetic : +, -, 0
    • NumberArithmetic : +, -, *, /, %, 0 - ArithmeticNegative : same as NumberArithmetic + Neg operator,
    • Number : +, -, *, /, %, 0, 1, ==, >=, min val, max val,
    • NumberNegative same as Number + Neg operator,

  • Float and Int related : Floating, Integer, IntegerUnsigned, IntegerSigned

• Useful macro : map_on_integer, map_on_integer_unsigned, map_on_integer_signed, map_on_float, map_on_number

Example using a map_on! macro

/// Define the `0` representation : The absorbing element of the multiplication such that `x * X::ZERO = X::ZERO`
pub trait Zero : Sized
{ 
    /// The absorbing element of the multiplication such that `x * X::ZERO = X::ZERO`
    const ZERO : Self;
}

macro_rules! impl_have_zero 
{ 
    ($primitive_name: ty) => 
    { 
        impl Zero for $primitive_name 
        { 
            const ZERO : Self = 0 as Self; 
        } 
    }; 
}

map_on_number!(impl_have_zero);
// and tada! Zero is now implemented for : (`i8`, `i16`, `i32`, `i64`, `isize`) + (`u8`, `u16`, `u32`, `u64`, `usize`) + (`f32`, `f64`)
