Fixes / Unit tests #24

Closed khaledkee closed 8 years ago

khaledkee commented 8 years ago

removed TestApp project
Added PolynomialEquation.Properties.Setting.Precision (default 2)
Made NegativeRankException public (For tests)
Added unit tests (not complete)
bug fixes:
- reverted ParsePolynomial and PolynomialParse
- reverted no roots exception
Notes:
- when polynomial precision is set to N all values less than 10 power negative N is equal to zero, for example: when precision is set to 2 and we multiplied 0.5 times 0.5X the result is 0.02X not 0.025X

_There is a problem calculating the middle term in any polynomial _x^n - p^2__

khaledkee commented 8 years ago

It's mainly because of the Add function. More precisely, if there is a term in the polynomial with the same degree, the Add function replaces it. However, in the recent commit, Add function discards zero terms before changing the old term.
