Hi Marcus, For 32 bit architectures, normally:
sizeof(float) == 4, sizeof(double) == 8 or 10 So there is no floating point overflow fortunately. E.g. http://www.iota-six.co.uk/c/b3_float_double_and_sizeof.asp PS: i think the date() and mktime() functions could be extended using the algorithms described in the date library, if anyone is interested. It would make date( ) and mktime() much more user friendly. "Marcus Boerger" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hello John, > > how does that help?
