It seems I'm missing something about that challenge. I tried making it a float with trying different padding, big/little endian and different formats when sending the solution, it just doesn't work :/

Any hints?

It's fussy about the length of your answer, so if you don't understand why your answer is rejected then try shorter versions.

...and to think all this time I thought it was a steneography challenge...

I hate this challenge, i have 2 numbers that seems possible, tried all kinds of lengths, nothing helped. (I have something with 8 and with -5)

You are on the right track with the 8something

takes much time if you have to wait half a minute between your tries. finally found the right length!

Without this thread i'd have expected the answer to be something that can be represented exactly as a decimal, thanks for the help on this somewhat “dirty” challenge.

Could someone post the right length? It seems I have tried every possible length but it won't work oO 8.something should be right though?

Ok, I finally got it. Try rounding to the sixth decimal digit.
This is odd since the wikipedia article says, the precision is about 7.225 decimal digits.

Thanks! Not one of the best challenges...

Which means, you can use the 7th digit to round *correctly* to 6 digits.

you're right, it can hold 7 decimal digits.
but have you forgot the one digit to the left of the point?

Ah this challenge sucks. I had that number at the beginning but I figured it was wrong because it wasn't a number that was recognizable. I thought it was going to be something like the sqrt(2) or gravity constant.

i m having trouble here.....
x.xxxxxx
with a '.' instead of ',' right?
and 6 digits after the point, or?!

this challenge really sucks ... i should have the correct number (8.xxxxxxxxxxxxxxxxxxxx) but it won't take my answer. I tried to round up / down to nearly every digit. I tried to round like wikipedia says (see: IEEE 754). Tried a ',' instead of '.' but nope ... everything is incorrect. That challenge is getting on my nerves. Not only cuz of the fact I have to wait 30 sec to try another value.
