Expressions
neighborhood type, type, double boolean return true if the first argument is in the neighborhood of
the second, meaning that the distance is less than or equal
to the third argument. The first two arguments can be any
type for which such a distance is defined. For composite
types, arrays, records, and matrices, then return true if the
first two arguments have the same structure, and each corresponding
element is in the neighborhood.

remainder double, double double remainder after division, according to the IEEE 754 floating-point
standard (see page 113).
round double long round to the nearest long, choosing the next greater integer
when exactly in between, and throwing an exception if out
of range. If the argument is NaN, the result is 0L. If the
argument is out of range, the result is either MaxLong or
MinLong, depending on the sign.
roundToInt double int round to the nearest int, choosing the next greater integer
when exactly in between, and throwing an exception if out
of range. If the argument is NaN, the result is 0. If the argument
is out of range, the result is either MaxInt or MinInt,
depending on the sign.
