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:

• basic arithmetic functions.
• comparison operators.
• functions for rounding numbers.
• exponential functions.

You can do output of all BCD numbers by using the OmniMark template formatting language and by using the format operator ("d" %).

The BCD library can throw the following exceptions:

• BCD0002 - String is Not a Valid BCD Value
• BCD0010 - Format Command Not Supported
• BCD0011 - Format Modifier Not Supported
• BCD0012 - Illegal Template Character
• BCD0013 - Template Overflow
• BCD0014 - Illegal Format String
• BCD0020 - Divide By Zero
• BCD0021 - Zero Raised to the Power Zero
• BCD0022 - Illegal Modulus
• BCD0023 - Illegal Rounding Base
• BCD0030 - Out Of Memory

To use ombcd, you must import it into your program using a statement like this:

  import "ombcd.xmd" unprefixed

(Please see the import topic for more on importing.)
