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