Struct Decimal

#[repr(packed(8))]
pub struct Decimal { /* private fields */ }

Expand description

XML Schema decimal datatype

It stores the decimal in a fix point encoding allowing nearly 18 digits before and 18 digits after “.”.

It stores the value in a i128 integer after multiplying it by 10¹⁸.
