`bit`
------
Calculates the bit of an integer.
```ruby

10.bit(-4) #=> 2
0b0100.bit(-3) #=> 0
```
`bit?`
------
Returns if it is a bit set.
```ruby
8.bit?(3) #=> true
8.bit?(2) #=> false
```
`bit_clear`
------
Clears a bit.
```ruby
4.bit_clear(2) #=> 0
```
`bitmask`
------
Calculates a bitmask of an integer.
```ruby
1.bitmask(6) #=> 7
7.bitmask(~2) #=> 5
```
`bitmask?`
------
Returns if it is a bitmask set.
```ruby
8.bitmask?(3) #=> true
8.bitmask?(2) #=> false
```
`combinatorial`
------
Calculates the combinatorial of an integer to another integer.
```ruby
50.combinatorial(49) #=> 50
50.combinatorial(50) #=> 1
8.combinatorial(4) #=> 70
```
`factorial`
------
Calculates the factorial of an integer.
```ruby
0.factorial #=> 0
1.factorial #=> 1
4.factorial #=> 24
```
`factors`
------
Calculates all the factors of an integer.
```ruby
24.factors #=> [1, 24, 2, 12, 3, 8, 4, 6]
```
`of`
------
Like `times` but returns a collection of the yield results.
```ruby
3.of { |i| i + 1 } #=> ['1', '2', '3']
```
`roman_numeral`
------
Converts an integer to a roman_numeral numeral.
```ruby
0.roman_numeral #=> ''
49.roman_numeral #=> 'XLIX'
-49.roman_numeral #=> '-XLIX'
```
`to_time` aka `to_t`
------
Returns a Time object for the given Integer.
```ruby
3.to_time #=> '1969-12-31 19:00:03.000000000 -0500'
```
