Struct fixnum::FixedPoint

#[repr(transparent)]
pub struct FixedPoint<I, P> { /* private fields */ }

Available on crate features i128 or i64 or i32 or i16 only.

Abstraction over fixed point numbers of arbitrary (but only compile-time specified) size and precision.

The internal representation is a fixed point decimal number, an integer value pre-multiplied by 10 ^ PRECISION, where PRECISION is a compile-time-defined decimal places count.

Maximal possible value: MAX = (2 ^ (BITS_COUNT - 1) - 1) / 10 ^ PRECISION Maximal possible calculation error: ERROR_MAX = 0.5 / (10 ^ PRECISION)

E.g. for i64 with 9 decimal places:

MAX = (2 ^ (64 - 1) - 1) / 1e9 = 9223372036.854775807 ~ 9.2e9
ERROR_MAX = 0.5 / 1e9 = 5e-10
