cZeros()
Catalog >
If a system is neither polynomial in all of its
variables nor linear in its unknowns, cZeros
() determines at most one zero using an
approximate iterative method. To do so, the
number of unknowns must equal the
number of expressions, and all other
variables in the expressions must simplify
to numbers.
A non-real guess is often necessary to
determine a non-real zero. For
convergence, a guess might have to be
rather close to a zero.

dbd()
Catalog >
dbd(date1,date2) ⇒ value
Returns the number of days between date1
and date2 using the actual-day-count
method.
date1 and date2 can be numbers or lists of
numbers within the range of the dates on
the standard calendar. If both date1 and
date2 are lists, they must be the same
length.
date1 and date2 must be between the
years 1950 through 2049.
You can enter the dates in either of two
formats. The decimal placement
differentiates between the date formats.
MM.DDYY (format used commonly in the
United States)
DDMM.YY (format use commonly in
Europe)
