It contains an - extensive equational theory (including, e.g., the AGM inequality), as well - as support for the ring tactic, and congruence tactics. - The following operations and notations are provided: - -<div class="paragraph"> </div> - - successor and predecessor - n.+1, n.+2, n.+3, n.+4 and n.-1, n.-2 - this frees the names "S" and "pred" - -<div class="paragraph"> </div> - - basic arithmetic - m + n, m - n, m * n - Important: m - n denotes TRUNCATED subtraction: m - n = 0 if m <= n. - The definitions use the nosimpl tag to prevent undesirable computation - computation during simplification, but remain compatible with the ones - provided in the Coq.Init.Peano prelude. - For computation, a module NatTrec rebinds all arithmetic notations - to less convenient but also less inefficient tail-recursive functions; - the auxiliary functions used by these versions are flagged with %Nrec. - Also, there is support for input and output of large nat values. - Num 3 082 241 inputs the number 3082241 - [Num of n] outputs the value n - There are coercions num >-> BinNat.N >-> nat; ssrnat rebinds the scope - delimiter for BinNat.N to %num, as it uses the shorter %N for its own - notations (Peano notations are flagged with %coq_nat). - -<div class="paragraph"> </div> - - doubling, halving, and parity - n.*2, n./2, odd n, uphalf n, with uphalf n = n.+1./2 - bool coerces to nat so we can write, e.g., n = odd n + n./2.*2. - -<div class="paragraph"> </div> - - iteration - iter n f x0 == f ( ..

All the inequalities refer to the same - constant "leq"; in particular m < n is identical to m.+1 <= n. - -<div class="paragraph"> </div> - - conditionally strict inequality `leqif' - m <= n ?= iff condition == (m <= n) and ((m == n) = condition) - This is actually a pair of boolean equalities, so rewriting with an - `leqif' lemma can affect several kinds of comparison. The transitivity - lemma for leqif aggregates the conditions, allowing for arguments of - the form ``m <= n <= p <= m, so equality holds throughout''. - -<div class="paragraph"> </div> - - maximum and minimum - maxn m n, minn m n - Note that maxn m n = m + (m - n), due to the truncating subtraction. - Absolute difference (linear distance) between nats is defined in the int - library (in the int.IntDist sublibrary), with the syntax `|m - n|. The - '-' in this notation is the signed integer difference. - -<div class="paragraph"> </div> - - countable choice - ex_minn : forall P : pred nat, (exists n, P n) -> nat - This returns the smallest n such that P n holds. - ex_maxn : forall (P : pred nat) m, - (exists n, P n) -> (forall n, P n -> n <= m) -> nat - This returns the largest n such that P n holds (given an explicit upper - bound). - -<div class="paragraph"> </div> - - This file adds the following suffix conventions to those documented in - ssrbool.v and eqtype.v: - A (infix) -- conjunction, as in - ltn_neqAle : (m < n) = (m != n) && (m <= n). - B -- subtraction, as in subBn : (m - n) - p = m - (n + p). - D -- addition, as in mulnDl : (m + n) * p = m * p + n * p. - M -- multiplication, as in expnMn : (m * n) ^ p = m ^ p * n ^ p. - p (prefix) -- positive, as in - eqn_pmul2l : m > 0 -> (m * n1 == m * n2) = (n1 == n2). - P -- greater than 1, as in - ltn_Pmull : 1 < n -> 0 < m -> m < n * m. - S -- successor, as in addSn : n.+1 + m = (n + m).+1. - V (infix) -- disjunction, as in - leq_eqVlt : (m <= n) = (m == n) || (m < n). - X - exponentiation, as in lognX : logn p (m ^ n) = logn p m * n in - file prime.v (the suffix is not used in ths file). - Suffixes that abbreviate operations (D, B, M and X) are used to abbreviate - second-rank operations in equational lemma names that describe left-hand - sides (e.g., mulnDl); they are not used to abbreviate the main operation - of relational lemmas (e.g., leq_add2l). - For the asymmetrical exponentiation operator expn (m ^ n) a right suffix - indicates an operation on the exponent, e.g., expnM : m ^ (n1 * n2) = ...; - a trailing "n" is used to indicate the left operand, e.g., - expnMn : (m1 * m2) ^ n = ...
