+
+## Description
+The `MONTHS_BETWEEN` function calculates the floating-point number of months
between two dates. It receives two date arguments and a optional boolean
argument.
+
+## Syntax
+
+```sql
+MONTHS_BETWEEN(<enddate>, <startdate> [, <round_type>])
+```
+
+## Parameters
+
+| Parameter | Description
|
+|-------------------|------------------------------------------------------------|
+| `<enddate>` | The ending date, representing the later date in the
difference calculation. Supports `DATE` (e.g., `YYYY-MM-DD`) or `DATETIME`
(e.g., `YYYY-MM-DD HH:MM:SS`) types. |
+| `<startdate>` | The starting date, representing the earlier date in the
difference calculation. Supports `DATE` (e.g., `YYYY-MM-DD`) or `DATETIME`
(e.g., `YYYY-MM-DD HH:MM:SS`) types. |
+| `<round_type>` | Whether to round the result to the eighth decimal place.
Supports `true` or `false`. Default is `true`. |
+
+## Return Value
+
+returns the floating-point number of months resulting from `<enddate>` minus
`<startdate>`
+
+result = (`<enddate>.year` - `<startdate>.year`) * 12 + `<enddate>.month` -
`<startdate>.month` + (`<enddate>.day` - `<startdate>.day`) / 31.0
+
+- When either `<enddate>` or `<startdate>` is NULL, or both are NULL, it
returns NULL
+- When `<round_type>` is `true`, the result is rounded to the eighth decimal
place.
+
+## Example
+
+```sql
+select months_between('2020-12-26','2020-10-25'),months_between('2020-10-25
10:00:00','2020-12-26 11:00:00',false);
+```
+
+```text
++-------------------------------------------+-------------------------------------------------------------------+
+| months_between('2020-12-26','2020-10-25') | months_between('2020-10-25
10:00:00','2020-12-26 11:00:00',false) |
++-------------------------------------------+-------------------------------------------------------------------+
+| 2.03225806 |
-2.032258064516129 |
++-------------------------------------------+-------------------------------------------------------------------+
+```
+
+**Note:**
+When both `<enddate>` and `<startdate>` are the last day of their respective
months, the function applies special handling.It returns the full month
difference without considering the fractional part based on days. This ensures
consistency when comparing the end of one month to the end of another.
