decimal

Decimal Floating Point arithmetic for rust based on the decNumber library.

The library provides d128 which is a 128-bit decimal floating point number. You can use it as other primitive numbers in Rust. All operators are overloaded to allow ergonomic use of this type.

To emulate literals a macro is used d128!.

Example

let x = d128!(1.234);
let y = d128!(1.111);
let z = d128!(2.345);
assert_eq(x + y, z);
