    Logic Calculator

    A Calculator to perform logical operations

    The Logic Calculator is an application useful to perform logical operations. It has three modes: (1) Evaluation of logic formulae: In this mode we have the basic boolean operations (negation, conjunction, disjunction, conditional and biconditional) so the user can insert the logic formula and the Logic Calculator displays the truth table along with the models of the formula. (2) Logical entailment: In this mode the user can insert a number of premises followed by a number of conclusions, so the Logic Calculator displays the truth table of each premise / conclusion and the result of whether or not these premises logically entail the given conclusions. (3) Conversion of a formula to Disjunctive Normal Form (DNF) and Conjunctive Normal Form (CNF): In this mode the user inserts a logic formula and the Logic Calculator outputs its representation in both a DNF and CNF.

    Financial Calculator (Windows setup)

    Financial Calculator (Windows setup)

    This is a program for more accurate financial calculations.

    This program has 11 parts for 11 different financial calculations. By this program, you could calculate financial calculations more accurate than normal programs. This program shows large numbers completely rather than in exponential form. However, still there are some limits; for example, very large numbers (more than 10000 digits) cannot be accepted as an input data. Some calculations also cannot be done with even much fewer digits too. It’s because of some limits for some computer calculations. You could translate this program into any language that you prefer. You have to use one of the official languages of this program to know how exactly putting the translation text lines. You could save the result of the calculation into the output file or save it into the database of the program, which is on top of each section. You could change the text color of the output file (except simple text files which cannot have any color).
