pyarts.internals.Rational¶

class pyarts.internals.Rational(numerator=0, denominator=None, *, _normalize=True)[source]¶

Rational number

This is a copy of fractions.Fraction with only the __repr__ function over- written to match ARTS style. That is 3/2 is represented as such rather than as “Fraction(3, 2)”. See original class for more information, limitations, and options

__init__(*args)[source]¶: Initialize self. See help(type(self)) for accurate signature.

Methods

`__init__`(*args)	Initialize self.
`as_integer_ratio`()	Return the integer ratio as a tuple.
`conjugate`()	Conjugate is a no-op for Reals.
`from_decimal`(dec)	Converts a finite Decimal instance to a rational number, exactly.
`from_float`(f)	Converts a finite float to a rational number, exactly.
`limit_denominator`([max_denominator])	Closest Fraction to self with denominator at most max_denominator.

Attributes

`imag`	Real numbers have no imaginary component.
`numerator`
`real`	Real numbers are their real component.
