# Data types are of C/C++. The values are got from
sizeof operator of C++ with g++ 9.1 on x86_64 Linux system. You may want to check the sizes with your own compiler.
Modified from https://www.colby.edu/chemistry/PChem/Hartree.html. Notice that in this version, significant figures are not considered because we do not want "1 Eh=220000 cm-1", although it is somehow correct.
If you want to add some other dimensions, please let me know.
