Detailed Description

This module is designed high precision numbers operations in enclave, a Trusted Execution Environment (TEE).

This module depends on project https://github.com/Safeheron/mpdecimal.git (branch v4.0.0_sgx), which is the Intel SGX version of mpdecimal (https://www.bytereef.org/mpdecimal). mpdeicmal has APIs in both C and C++ languages, only C APIs are used in this module. (See https://www.bytereef.org/mpdecimal/doc/libmpdec/index.html)

The main functions are as follows:

Note: Big number operations and precision control might cause exceptions, please refer comments for each functions.
