You can use the BCD (Binary Coded Decimal) library to create and manipulate BCD numbers in your programs.
BCD numbers are useful for financial and some scientific calculations.
The syntax of most BCD functions is the same as that for the corresponding floating point functions, and you can safely import both of them - omfloat.xmd and ombcd.xmd - in a single OmniMark program.
There are several categories of external functions in the BCD library, all of which use the same operators as in the floating point library and in core OmniMark:
You can do output of all BCD numbers by using the OmniMark template formatting language and by using the format operator ("d" %).
This is a complete list of the BCD library external exceptions that may be
thrown back to the calling OmniMark program. These are all catchable using
To use ombcd, you must import it into your program using a statement like this:
import "ombcd.xmd" unprefixed
(Please see the
