Explanation is completely unclear that the decimal mark should (usually) be either a dot or a comma in single quotes. While integers 44 and 46 are the equivalent, that is not helpful to newcomers to Euphoria.
include std/convert.e
atom n1 = to_number("12,345.95")
? n1
set_decimal_mark(',')
atom n2 = to_number("12.345,95")
? n2
Also, needs results to be shown!
