DESCRIPTION
TCioinaEval class can parses and evaluates a mathematical expression given as a string.

BASE CONCEPTS
Fast parsing speed: e.g. 9-10 faster than UCalc 2.0.
Fast calculating speed: e.g. 40 faster than TKAParser 1.02, 6-14 faster than Mathematica 4.1, 2-10 faster than
TRyFormulaEval 2.0, in general it is faster than UCalc 2.0 and in particular it is faster than Parser 10.1.
Low dynamic memory request: e.g. 2-6 lower than Mathematica 4.1.
High calculation stability
Full calculation string export to Mathematica 4.1.

MAIN FEATURES

· accept operators: + - * / ^ =
· accept user defined functions and constants
· function accept any number of parameters and varying number of parameters
· function's parameter can be string or any valid expression
· error handling with localizing points of failure
· optimized calculations (constant parts of expression are calculated)
· parsed expression can be retrieved (added parenthesis)
· expression can be differentiated
· accept the export to Mathematica 4.1 form
· can parses an expressions array
· cross-platform compilation (Windows-Linux)
· variables automatic check possibility
· built-in small help
· exception control

TESTS
I have tested CioinaEval 7.1.0.0 with a large math expression obtained from Sin(x)^Cos(x)
by differentiating 5 and 6 times respectivly.
