Function Names
lengthDescription
This function returns the number of characters in the string. New line symbols count as 1 character. If the value provided is not a string, then it will be converted to a string first.
Attention: For numerals and dates with available string context, the string will be used.
A simpler approach is to use {} behind the string, referred as length of strings. This simplified appraoch runs faster, but assumes
a string value to be provided all times.
