ILE C/C++ Programmer's Guide
When you are working with ILE C++, the _DecimalT class template
allows representation of up to 31 significant digits, including integral and
fractional parts. The fractional part of a dollar can be represented
accurately by two digits following the decimal point.
- Note:
- You do not have to use floating point arithmetic. Floating
point is more suitable for scientific and engineering computations, which
often use numbers that:
- Are much larger than the largest packed decimal variable can store
- Are much smaller than the smallest packed decimal, but do not have enough
precision for commercial use
The same declarations and operators that you use on other data types, such
as float, can be applied to _DecimalT class templates, with the
exception of unions and bitwise operators that do not apply to
_DecimalT class templates.
You can:
- Declare type definitions, arrays, and structures that have
_DecimalT class templates.
- Apply arithmetic, relational, assignment, comma, conditional, equality,
logical, and unary operators on the _DecimalT class
template.
- Pass _DecimalT class templates in function calls. The
_DecimalT class template is compatible with packed decimal
representations in ILE languages.
- Define macros, and call library functions with _DecimalT class
templates.
- View the _DecimalT class template when you use the ILE system
debugger.
- Note:
- When you view a _DecimalT class template, none of the operators
are accessible from the debugger. For information on the ILE system
debugger, see Part 3, Debugging Programs.
