Struct rsass::value::Number

pub struct Number { /* private fields */ }

The actual number part of a numeric sass or css value.

Only the actual numeric value is included, not any unit. Internally, a number is represented as either a rational or a floating-point value as needed.

Implementations

impl Number

pub fn rational(num: i64, denom: i64) -> Self

Create a rational number.

pub fn as_ratio(&self) -> Result<Rational, BadNumber>

Get this number as a rational number.

If the value is bignum rational or floating point, it is approximated as long as it is withing range, otherwises an error is returned.

pub fn ceil(&self) -> Self

Get a copy of this number, rounded away from zero.

pub fn floor(&self) -> Self

Get a copy of this number, rounded towards zero.

pub fn round(&self) -> Self

Get a copy of this number, rounded to nearest integer.

pub fn abs(self) -> Self

Computes the absolute value of the number, retaining the flags.

pub fn is_negative(&self) -> bool

Return true if this number is less than zero.

pub fn into_integer(self) -> Result<i64, Self>

Returns true if the number is an integer.

pub fn to_integer(&self) -> Option<i64>

Converts to an integer, rounding towards zero.

An integer that is too big to fit in an i64 returns None.

pub fn powi(self, p: i32) -> Self

Computes self^p.

pub fn format(&self, format: Format) -> Formatted<'_, Self>

Get a reference to this Value bound to an output format.
