[precision] is SOME n, where n is the number of significant bits in an
integer. In Moscow ML n is 31 in 32bit architectures and 63 in 64bit
architectures.
[minInt] is SOME n, where n is the most negative integer.
[maxInt] is SOME n, where n is the most positive integer.

[*]
[+]
[] are the usual operations on integers. They raise Overflow if
the result is not representable as an integer.
[abs] returns the absolute value of its argument. Raises Overflow
if applied to the most negative integer.
[div] is integer division, rounding towards minus infinity.
Evaluating i div 0 raises Div. Evaluating i div ~1 raises
Overflow if i is the most negative integer.
[mod] is the remainder for div. If q = i div d and r = i mod d then
it holds that qd + r = i, where either 0 <= r < d or d < r <= 0.
Evaluating i mod 0 raises Div, whereas i mod ~1 = 0, for all i.
[quot] is integer division, rounding towards zero. Evaluating
quot(i, 0) raises Div. Evaluating quot(i, ~1) raises Overflow if i
is the most negative integer.
[rem(i, d)] is the remainder for quot. That is, if q = quot(i, d)
and r = rem(i, d) then d * q + r = i, where r is zero or has the
same sign as i. If made infix, the recommended fixity for quot and
rem is
infix 7 quot rem
[min(x, y)] is the smaller of x and y.
[max(x, y)] is the larger of x and y.
[sign x] is ~1, 0, or 1, according as x is negative, zero, or positive.
[<]
[<=]
[>]
[>=] are the usual comparisons on integers.
[compare(x, y)] returns LESS, EQUAL, or GREATER, according
as x is less than, equal to, or greater than y.
[sameSign(x, y)] is true iff sign x = sign y.
[toInt x] is x (because this is the default int type in Moscow ML).
[fromInt x] is x (because this is the default int type in Moscow ML).
[toLarge x] is x (because this is the largest int type in Moscow ML).
[fromLarge x] is x (because this is the largest int type in Moscow ML).
[fmt radix i] returns a string representing i, in the radix (base)
specified by radix.

BIN signed binary (base 2) ~?[01]+
OCT signed octal (base 8) ~?[07]+
DEC signed decimal (base 10) ~?[09]+
HEX signed hexadecimal (base 16) ~?[09AF]+
[toString i] returns a string representing i in signed decimal format.
Equivalent to (fmt DEC i).
[fromString s] returns SOME(i) if a decimal integer numeral can be
scanned from a prefix of string s, ignoring any initial whitespace;
returns NONE otherwise. A decimal integer numeral must have form,
after possible initial whitespace:
[+~]?[09]+
[scan radix getc charsrc] attempts to scan an integer numeral
from the character source charsrc, using the accessor getc, and
ignoring any initial whitespace. The radix argument specifies the base
of the numeral (BIN, OCT, DEC, HEX). If successful, it returns
SOME(i, rest) where i is the value of the number scanned, and rest
is the unused part of the character source. A numeral must have
form, after possible initial whitespace:
