Visual Basic, in the immediate window, First as a Single Precision calculation, then as Double Precision, and finally using the Decimal Variant subtype. :)

(note that "?n" in the immediate window is the same as "Print n")
Code: [Select]
?111111111! * 111111111!
 1.234568E+16
?111111111# * 111111111#
1.23456789876543E+16
?cdec(111111111) * cdec(111111111)
