@ -131,23 +131,23 @@ def _sum(data, start=0):
--------
>>> _sum([3, 2.25, 4.5, -0.5, 1.0], 0.75)
(<class 'float'>, Fraction(11, 1), 5)
(<class 'float' ...>, Fraction(11, 1), 5)
Some sources of round-off error will be avoided:
>>> _sum([1e50, 1, -1e50] * 1000) # Built-in sum returns zero.
(<class 'float'>, Fraction(1000, 1), 3000)
(<class 'float' ...>, Fraction(1000, 1), 3000)
Fractions and Decimals are also supported:
>>> from fractions import Fraction as F
>>> _sum([F(2, 3), F(7, 5), F(1, 4), F(5, 6)])
(<class 'fractions.Fraction'>, Fraction(63, 20), 4)
(<class 'fractions.Fraction' ...>, Fraction(63, 20), 4)
>>> from decimal import Decimal as D
>>> data = [D("0.1375"), D("0.2108"), D("0.3061"), D("0.0419")]
>>> _sum(data)
(<class 'decimal.Decimal'>, Fraction(6963, 10000), 4)
(<class 'decimal.Decimal' ...>, Fraction(6963, 10000), 4)
Mixed types are currently treated as an error, except that int is
allowed.
