Part I is freeware shipping with the sources.

Part II (also known as DECMath) is not available as freeware and it's distribution is 
only allowed for noncommercial or academical use. Please check back with the original 
author regarding any commercial use. Part II is only available in the archives for 
compatibility reasons. It is distributed as precompiled Delphi unit binaries
for D5, D6 and D7.
