Struct bitcoin::util::decimal::Decimal

pub struct Decimal { /* fields omitted */ }

A fixed-point decimal type

Methods

impl Decimal

pub fn new(mantissa: i64, exponent: usize) -> Decimal

Creates a new Decimal

pub fn mantissa(&self) -> i64

Returns the mantissa

pub fn exponent(&self) -> usize

Returns the exponent

pub fn integer_value(&self, exponent: usize) -> i64

Get the decimal's value in an integer type, by multiplying by some power of ten to ensure the returned value is 10 ** exponent types the actual value.

pub fn nonnegative(&self) -> bool

Returns whether or not the number is nonnegative
