HOBDCalc is an little library for converting decimal values (signed integers or floating-point values) in an string representing the value in following bases.
- Binary base (2).
- Octal base (8).
- Hexadecimal base (16).
The values are converting in an string in the wanted base.
And HOBDCalc provide the back conversion functions:
from an string in base 2, 8 or 16 to the corresponding value in decimal base.
That's not all because HOBDCalc implement the basic operations to apply on the strings in the supported base.
- Addition from 2 strings in base 2, 8 or 16.
- Substraction from 2 strings in base 2, 8 or 16.
- Multiplication from 2 strings in base 2, 8 or 16.
- Division from 2 strings in base 2, 8 or 16.
Either as integer values or as floating-point values.

By compilation of your programm simply link the HOBDCalc library.
If this fail try to link first the HOBDCalc library and after the math library.
For the base conversions for floating-points values use the double type instead of the long double type by usage of a cast.
Because libHOBDCalc compute internally with the type long double type but if you want an fully exact returned value use a cast to the double type.
like in the provide assertions file of the library: hobdcalc_assertions.c which demonstrate the exactitude of libHOBDCalc with an correct usage and to put libHOBDCalc to the proof.
I failed to implement the under|over flow detection by operations functions who deal with the type long double.
If you know how to detect so an under|over flow thank's to contact me at: <mrcyberfighter@gmail.com>.
Read the manpages available at section 3 for usage of libHOBDCalc:
- $ man binaddbin
- $ man bindivbin
- $ man binfloataddbinfloat
- $ man binfloatdivbinfloat
- $ man binfloatmultbinfloat
- $ man binfloatsubbinfloat
- $ man binfloattofloat
- $ man binmultbin
- $ man binsubbin
- $ man bintoint
- $ man floattobinfloat
- $ man floattohexfloat
- $ man floattooctfloat
- $ man hexaddhex
- $ man hexdivhex
- $ man hexfloataddhexfloat
- $ man hexfloatdivhexfloat
- $ man hexfloatmulthexfloat
- $ man hexfloatsubhexfloat
- $ man hexfloattofloat
- $ man hexmulthex
- $ man hexsubhex
- $ man hextoint
- $ man hobdcalc
- $ man inttobin
- $ man inttohex
- $ man inttooct
- $ man octaddoct
- $ man octdivoct
- $ man octfloataddoctfloat
- $ man octfloatdivoctfloat
- $ man octfloatmultoctfloat
- $ man octfloatsuboctfloat
- $ man octfloattofloat
- $ man octmultoct

Thank's to my beloved mother, my family and the doctors.
