    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).
