I'm new user on SMath and my Engish is poor. SMath likes me but I don't see how to adjust (in properties) calculation precision. My question is: why programm calculate eg. 75 x 175 = 13100, not 13125? It's precision only I now, but how to adjust it?
And once more question: is in SMath posibility replace variables as a value in equations? (explicity function).
Thanks for answer.
