Can You Work With Decimal Data Types in C ?

Support for Decimal Data Types in C

Question:

Is it possible to utilize decimal data types like decimal32, decimal64, or decimal128 within C programs?

Answer:

The Decimal TR includes classes that are not universally implemented across compilers. Certain compilers, such as gcc, adhere to the C Decimal TR and extend it to C .

Historically, an open-source implementation of the C Decimal TR existed, but it is currently unavailable. If your compiler does not natively support decimal data types, you may consider creating a wrapper for IBM's decNumber library.

To address this issue in future versions of C , an initiative is underway to update the Decimal TR. The goal is to refine the TR into a complete proposal for the upcoming C committee meeting (in Bristol in April). The objective is to have it incorporated into the C standard, potentially in the 2014 revision.

It is important to note that the current implementation is part of a closed-source project. Therefore, the decision to open-source it is beyond the author's control, although there is optimism for its potential release in the future.
