Using Decimal Data Types in C
In C , decimal data types like decimal32, decimal64, and decimal128 are provided by the Decimal TR (Technical Report). However, the implementation of these types varies across compilers.
Compiler Support
- Some compilers, such as gcc, implement the Decimal TR and provide the corresponding extensions in C .
- Other compilers may not support these types.
Options for Using Decimal Data Types
If your compiler does not support decimal types, consider the following options:
- IBM decNumber Library: Create a wrapper for this library to access decimal functionality.
- TR Proposal: Engage in the efforts to update and standardize the Decimal TR. An implementation is available, but its public release is uncertain.
Note: The Decimal TR and its implementation are subject to change as the standardization process progresses.
