# Like val(), but return the value parsed as float (or 0, if the value is not numeric). Also works for non-input elements (using the element's text content as value).
#
# Thousands delimiters (",") are handled correctly.
# German thousands delimiters (".") and separators (",") are handled correctly if the lang attribute of the input element (or any of its parent elements) is set to "de".
#
# Options:
# ignoreCurrencySign: If true, values with leading currency signs (€, $) are considered numeric and parsed correctly.
# nullOnError: If true, null is returned (instead of 0) if the value is not numeric.
