**months**() Link

Enables the use of time calculations and declarations, like
`45.minutes + 2.hours + 4.years`

.

These methods use Time#advance for
precise date calculations when using `from_now`

,
`ago`

, etc. as well as adding or subtracting their results from
a Time object.

```
# equivalent to Time.now.advance(months: 1)
1.month.from_now
# equivalent to Time.now.advance(years: 2)
2.years.from_now
# equivalent to Time.now.advance(months: 4, years: 5)
(4.months + 5.years).from_now
```

While these methods provide precise calculation when used as in the
examples above, care should be taken to note that this is not true if the
result of `months`

, `years`

, etc is converted before
use:

```
# equivalent to 30.days.to_i.from_now
1.month.to_i.from_now
# equivalent to 365.25.days.to_f.from_now
1.year.to_f.from_now
```

In such cases, Ruby's core Date and Time should be used for precision date and time arithmetic.

**multiple_of?**(number) Link

Check whether the integer is evenly divisible by the argument.

```
0.multiple_of?(0) # => true
6.multiple_of?(5) # => false
10.multiple_of?(2) # => true
```

**ordinal**() Link

Ordinal returns the suffix used to denote the position in an ordered sequence such as 1st, 2nd, 3rd, 4th.

```
1.ordinal # => "st"
2.ordinal # => "nd"
1002.ordinal # => "nd"
1003.ordinal # => "rd"
-11.ordinal # => "th"
-1001.ordinal # => "st"
```

**ordinalize**() Link

Ordinalize turns a number into an ordinal string used to denote the position in an ordered sequence such as 1st, 2nd, 3rd, 4th.

```
1.ordinalize # => "1st"
2.ordinalize # => "2nd"
1002.ordinalize # => "1002nd"
1003.ordinalize # => "1003rd"
-11.ordinalize # => "-11th"
-1001.ordinalize # => "-1001st"
```
