-TODO: Add the content of Number Patterns for Formatting and Parsing
+### Description
+
+Functions such as `to_number` and `try_to_number` support converting between
values of string and
+Decimal type. Such functions accept format strings indicating how to map
between these types.
+
+### Syntax
+
+Number format strings support the following syntax:
+
+```
+ { ' [ S ] [ L | $ ]
+ [ 0 | 9 | G | , ] [...]
+ [ . | D ]
+ [ 0 | 9 ] [...]
+ [ L | $ ] [ PR | MI | S ] ' }
+```
+
+### Elements
+
+Each number format string can contain the following elements (case
insensitive):
+
+- **`0`** or **`9`**
+
+ Specifies an expected digit between `0` and `9`.
+
+ A `0` to the left of the decimal point indicates that at least this many
digits must be present.
