Hi!

Can anybody describe me (or give me a link) how the internal conversion of integer/double values work? I try to analyse a file written by visual basic with integer / double values when I look to it by a Hex-Editor.

Integer and Double are completely different. Integers and Longs can be converted to HEX easily using the <font color=blue>Hex</font color=blue> function, but I dont think Doubles can.

Hi!

I'm not searching for a funtion who do it, but for the algorithm because I want to generate a file on a other system (IBM-EBCDIC-World) I have to know the details
about such a function, what it does internal.

Can anybody help me?

According to MSDN, the double type consists of
1 bit for the sign
11 bits for the exponent
52 bits for the mantissa (+1 implied high order bit)

for a total of 64 bits (+1 implied).

The implied bit business refers to the fact that a binary mantissa always starts with 1. Therefore, the most significant bit can be left out since we know it is always one.
