Main API

Reconstruct rounded numbers, or the bounds of the numbers behind them.

reround()

General interface to reconstructing rounded numbers

unround()

Reconstruct rounding bounds

Individual rounding procedures

Each of these can also be reached through reround()’s rounding argument.

round_up_from() round_down_from() round_up() round_down()

Common rounding procedures

round_ties_up() round_ties_down() round_ties_away() round_ties_zero() round_ties_even()

Rounding procedures named by their tie-breaking rule

round_ceiling() round_floor() round_trunc() anti_trunc() round_anti_trunc()

Rounding in one direction

round_ties_to_even() round_ties_to_away() round_toward_positive() round_toward_negative() round_toward_zero()

IEEE 754 rounding standard

Fractions and bias

reround_to_fraction() reround_to_fraction_level()

Rounding to the nearest fraction

rounding_bias()

Compute rounding bias

For package developers

The exact-integer form of unround()’s bounds, the whole-number sums they admit, and the meaning of a "ties_*" string, for building consistency tests on.

bound_numerators()

Rounding bounds as exact integers

sum_range()

Whole-number sums behind a rounded mean

resolve_ties_rounding()

Resolve a "ties_*" rounding string
