Struct FixedI128

pub struct FixedI128 { /* private fields */ }

Fixed precision u128 - upper 64 bits is value, lower 64 bits are the fractional portion of the value. Each fractional portion is 1/i64::MAX ~= 5.4210e-20 or 0.000_000_000_000_000_000_054_210, or about 54.2 zepto, and can accurately represent SI-prefixes milli/1e-3, micro/1e-6, nano/1e-9, pico/1e-12, femto/1e-15, and atto/1e-18. This is probably overkill for what you need. The whole portion can represent i64::MIN (-9_223_372_036_854_775_808) -> i64::MAX (9_223_372_036_854_775_807)
