Calcc 0.1.1a

Calcc is a useful command-line calculator (32/64 bit numbers) which supports multiple input and output formats (hex, decimal, octal, base4, binary, string and IPv4/v6 addresses, base64, percentage, time), parenthesis and the following operators: complement, not, shift, rotate, xor, and, or, power, root, byte and bit swapping, multiplication, division, modulus, addition and substraction.
Can be used also like a quick and easy to use numbers converter.
I have decided to write this program for requirement (Im lost without a command-line calculator) just because after many time and searches on Internet I have never found something similar supporting what I needed.
It is specific for people which use C and assembly and need a fast and simple way for computing particular calculations often used in these programming languages but its also perfect for who wants to do 1+2 without reading a boring manual and without using tons of different programs for converting and reconverting inputs and outputs from a format to another one.
The program supports different types of input formats (default is decimal) and are recognized through a character before each number:
0x = hexadecimal example: 0x41
$ = hexadecimal example: $41
h = hexadecimal example: h41
o = octal example: o101
b = binary example: b1000001
i = IP address (v4 or v6) example: i1.2.3.4 or 1.2.3.4
or 1.2.3.4.5.6
q = base_four example: q1001
t = time hh:mm:ss example: t12:34:53
if you use t0 will be get the current system time
c = percentage example: 200 - c10 (its like 200 - 10%)
200 = c10 (returns the 10%)
must be specified ever at right of the operation
= decimal (default) example: 65
All the input types are case insensitive, so 0x7a is the same of 0X7A.
IP addresses (both ipv4 and ipv6 supported) are automatically recognized also without specifying the i char, if the program finds at least 3 dots in a number considers it an IP address.
Enhancements:
- Localtime was substituted with gmtime (UTC time visualization).
