A console program that converts a number (or text) from one numerical system into another different numerical system.

+

+Compiling

+

This program create an executable (or many) that will convert a number from one numerical system into another one.

+

For example, you may want to convert a hexadecimal number into a ternary number. You may use this program.

+

You first need to define the proprieties of the numerical systems. These proprieties are defined in the compilation process (as compilation flags).

+

For example, let's make the hexdecimal numerical system with numerals from 0-f, with a infinite 0 and it start counting on 1. So, our hexadecimal system will need the following compilation flags:

-DFROM_NUMERICALS=\"0123456789abcdef\" -DFROM_FIRST_NUMBER_VOID -DFROM_INFINITE_BASE

+

if you want the units place of this numerical system to be on the right side, add -DFROM_UNITS_ON_THE_END.

+

Now, for the ternary system let's make with numerals from 1-3, 1 is not infinite and it start counting on 1. Use this flags:

-DTO_NUMERICALS=\"123\"

+

if you want the units place of this numerical system to be on the right side, use -DTO_UNITS_ON_THE_END.

+

Now, to create the executable to translate a number for these two numerical system, join all of this together and compile using this:

$ c99 -DFROM_NUMERICALS=\"0123456789abcdef\" -DFROM_FIRST_NUMBER_VOID -DFROM_INFINITE_BASE -DFROM_UNITS_ON_THE_END -DTO_NUMERICALS=\"123\" -DTO_UNITS_ON_THE_END numericx.c -o hex-to-ternary

+

This creates the hex-to-ternary executable with can be used to convert numbers from hexadecimal to ternary!

+

+Pre-defined executable compilation

+

There are many pre-defined compilation of executables on the Makefile. Take a look at the Makefile to know them. Or you can run make to get all of the pre-defined executables. make clean to delete them.

+

+Compilation flags meanings

+

There are two categories for the compilation flags: the FROM category and the TO category.

+

FROM flags are the numerical system definitions of the argument number.

+

TO flags are the numerical system definitions of the number result.

+

Below, are the meanings of the FROM flags. The TO flags are the same as the FROM flags, with a switch of the FROM_ to a TO_.

+ + + + + + + + + + + +

Flag	Meaning
FROM_NUMERALS	Define the numerical system numerals of the 'from'
FROM_UNITS_ON_THE_END	Defines the units case to be on the end (on the right) for the 'from'
FROM_FIRST_NUMBER_VOID	Defines the first number as a "not counting" for the 'from'
FROM_INFINITE_BASE	Defines the first number to be infinite, for the 'from' (for example, if the first numeral is 0, then 0 == 00 == 000 == 0000 ... . Or if the first numeral is 1, then 1 == 11 == 111 ...)

+

There is also the DEBUG flag, which will show all the steps that you number walked through. Remember: you use -DDEBUG as an compiler argument.
