Reducing to an interval modulo its length

This file defines operations that reduce a number (in an Archimedean LinearOrderedAddCommGroup) to a number in a given interval, modulo the length of that interval.

Main definitions

• toIcoDiv hp a b (where hp : 0 < p): The unique integer such that this multiple of p, subtracted from b, is in Ico a (a + p).
• toIcoMod hp a b (where hp : 0 < p): Reduce b to the interval Ico a (a + p).
• toIocDiv hp a b (where hp : 0 < p): The unique integer such that this multiple of p, subtracted from b, is in Ioc a (a + p).
• toIocMod hp a b (where hp : 0 < p): Reduce b to the interval Ioc a (a + p).
