Function Names
min, max ignore zero, min ignore blanks, max, max ignore zero, max ignore blanksDescription
min / max…: Compares all values inside the function parameter or parameter set together, using type checking and comparison rules as given for
the binary operators < (for min) and > (for max).
The suffix ... ignore zero excludes all zero values and blank (=zero) dates.
The suffix ... ignore blanks excludes all strings with blank contents. Note: Blank dates can be ignored with ... ignore zero. For the functions desccribed here, strings containing white spaces only are considered blank, too.
Providing mixed types, e.g. a combination of numerals and strings, will assert exceptions. Only the ... ignore blanks suffix tolerates
blank strings in the parameters where the others are other types, e.g. numerals.

Examples
echo( "dates, 0 ignored : ", min ignore zero( date(""), date("2020-03-23"), date("2020-03-20") ) );
echo( "dates compared : ", min ( date(""), date("2020-03-23"), date("2020-03-20") ) );
echo( "numbers w/o blanks: ", min ignore blanks( 5, 8, "", 1 ) );
echo( "strings : ", max( "He", "he", "hi", "Hi" ) ); // Max = last in alphabetic order
// echo( "causes exception : ", max ( 1, a, 2, b ) ); // Commented out because it's wrong.Output
