+### 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

Review Comment:
   Shall we have the highlights for all the functions?
   E.g.
   ```
   to_number(string, format);
   try_to_number(string, format);
   ```
