In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically 0 and 1.
21+
22+
23+
## Installation
24+
25+
*Installing using [Clib](https://github.com/clibs/clib)*
26+
27+
```sh
28+
$ clib install abranhe/binary.c
29+
```
30+
31+
## Usage
32+
33+
```c
34+
#include <stdio.h>
35+
#include "binary.h"
36+
37+
int main() {
38+
printf("%d\n", is_binary(1010));
39+
// 1
40+
printf("%ld\n", to_decimal(10000000011));
41+
// 1027
42+
printf("%lld\n", to_binary(1000));
43+
// 1111101000
44+
}
45+
```
46+
47+
## API
48+
49+
#### `bool is_binary(long binary);`

###### Params:
54+
55+
- `binary`: long binary number
56+
57+
#### `long to_decimal(long long binary);`
58+
59+
*Returns a long decimal number from a binary number*
60+
61+
###### Params:
62+
63+
- `binary`: long binary number
64+
65+
#### `long long to_binary(long decimal);`
66+
67+
*Returns a binary number from a decimal number*
68+
69+
###### Params:
70+
71+
- `decimal`: a long decimal number
