Function Names
best typeDescription
In case the input parameter is a string, then it will be converted to the best type, depending on the contents. All non-string types (numerals, sets, dates, booleans voids) will be passed through without modifications Following rules apply for strings provided as parameters
- If the contents look like number, e.g. "123.45", then a conversion to numerals takes plae.
- If the contents equals true or false, then a converion to boolean takes place.
- Followng rules apply if unabiguous dates and/or times are provided:
- "YYYY-MM-DD": Dates
- "hh:mm:ss": Times
- "YYYY-MM-DD hh:mm:ss": Dates with times
- "0000-00-00" Blank dates
- Any other characters, including spaces before or after dates, will suppress date conversion.
- If the 2nd parameter is true, then strings will be converted to parameters sets if the contents look like sets, e.g. contents inside braces { ... }. The elements must be separated with commas.
- In all other cases, the string contents are passed through without changes.
