/* hobdcalc can compute in the
* -) binar
* -) octal
* -) hexadecimal
* bases without problems.
*
* Arithmetics functions take the 2 operand as string
*
* whose you can get with the conversion functions who take as first argument an value
* and as second a pointer to a buffer for containing the result (size 128).
*
* The reverse functions take a string as argument and return the [integer|float] result.
*
* The limits values are for:
* integer: long long [-9223372036854775808 - 9223372036854775807].
* floats : long double 15 digits precision.
*
* You must link the type generic math file with:
* $ gcc hobdcalc.c -lm
* to compil the code.
*
* You can use the test function:
* for understanding the code.
*
* Note: I don't care about strtold() or strtoll() and the %x %o %a placeholders, only raw computing, because i made
* bad experience with it during developpment and testing.
*
* I hope this little calculator functions will be usefull for you.
