SEUIF97: the high-speed shared library of IAPWS-IF97

SEUIF97 is the high-speed shared library of IAPWS-IF97. It is suitable for computation-intensive calculations,such as heat cycle calculations, simulations of non-stationary processes, real-time process monitoring and optimizations. Through the high-speed library, the results of the IAPWS-IF97 are accurately produced at about 3x speed-up compared to the repeated squaring method for fast computation of integer powers, 10x speed-up compared to the math.pow() of the C standard library. The shared libraries for Windows and Linux(X86/X64): Windows32/64: libseuif97.dll; Linux64: libseuif97.so The binding APIs for the programming languages: Python, C/C++, Excel VBA, MATLAB, Fortran, Java, C#, Modelica, Rust, Pasca
