Constants
- rcdesign.is456.constants.gamma_c: Fraction = Fraction(3, 2)
This class implements rational numbers.
In the two-argument form of the constructor, Fraction(8, 6) will produce a rational number equivalent to 4/3. Both arguments must be Rational. The numerator defaults to 0 and the denominator defaults to 1 so that Fraction(3) == 3 and Fraction() == 0.
Fractions can also be constructed from:
numeric strings similar to those accepted by the float constructor (for example, ‘-2.3’ or ‘1e10’)
strings of the form ‘123/456’
float and Decimal instances
other Rational instances (including integers)
- rcdesign.is456.constants.gamma_s: Fraction = Fraction(23, 20)
This class implements rational numbers.
In the two-argument form of the constructor, Fraction(8, 6) will produce a rational number equivalent to 4/3. Both arguments must be Rational. The numerator defaults to 0 and the denominator defaults to 1 so that Fraction(3) == 3 and Fraction() == 0.
