Struct FixedPoint32

pub struct FixedPoint32 {
    pub value: u64,
}

Define a fixed-point numeric type with 32 fractional bits. This is just a u64 integer but it is wrapped in a struct to make a unique type. This is a binary representation, so decimal values may not be exactly representable, but it provides more than 9 decimal digits of precision both before and after the decimal point (18 digits total). For comparison, double precision floating-point has less than 16 decimal digits of precision, so be careful about using floating-point to convert these values to decimal.

Fields

value: u64
