hello,

can somebody explain what this value 1.343646e+111 means in number. (please)

this is the result of 62^62

thanks,

1.343646 × 10¹¹¹
If my math is still up to scratch 1343646 followed by 111 zeros.
You move the decimal point to the right with a plus symbol, or left with a minus symbol.

of course it is a 1343646 followed by 105 zeros!

Because after the decimal point there are written 6 digits, you need to substract them from 111

111-6 =105

1e+111 = 1 x 10¹¹¹ is a 1 followed by 111 zeros

and...
1.0e+111  = 1.0 x 10¹¹¹ is a 10 followed by 110 zeros

and so..
1.34e+111 = 1.34 x 10¹¹¹ is a 134 followed by 109 zeros



1.6e+1 = 1.6 x 10¹ is a 16

1.6e+2 = 1.6 x 10² is a 160

1.6e+0 = 1.6 x 10⁰ is a 1.6

1.6e-1 = 1.6 x 10^-1 is a 0.16

Which language were you using? In C/C++, for example, the "^" operator means bitwise XOR, while in BASIC it means "power to"

ok, i understand. 

thanks

yes i wanted to calculate a 'power of'

this was to calculate the number of possible passwords if all az AZ 09 characters are used
26+26+10 = 62
62^62 = 1.343646e+111 = 1343646000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000


an interesting website to check if your password is easy to find (with brute force ) : 
https://www.security.org/how-secure-is-my-password/

your all forgetting that your asuming its base 10, could be base 16 or something , sorry just like jigging things up

I think that isn't quite right - if you want a 62 character password which uses all 62 available characters, then the number available for each position goes down by one each time (because some have already been used), so the total number is 62! ( 62 factorial, or 62 x 61 x 60 x ... 2 x 1), which is still an astronomically large number (about 3 x 10^85), but much much smaller than 62^62!

@DaiHard,
RemiD is using this for passwords, which normally allows repeated characters - in this case from a choice of 62.
And yes, you're right that the factorial is only if each character can be used once, but there's no real reason for that restriction.

And now watch what happens with your brute force technique if the server with the login account enforces a few second delay as a security measure between each login attempt....gonna take a lot longer than what you expect.....oh...and locks the account if there are too many wrong attempts requiring a direct person-to-person contact to unlock again should that trigger be switched.

if i was the adminstrator, after a fail is triggered , I would root the login to a dummy and keep the logger busy heheheeee

maybe some fake login then logged out to frustrate them heheeee 

I would have a lot of fun as admin  

hi

i have encountered such a weird value again.

but in this case the symbol at the end is negative ( - minus) :
5.26316e-004

the result of 0.10 / 190

if i understand correctly, this would equal to :
0.000526316

0.000526316 * 190 = 0.1

correct ?

yes it seems...

Yes. A negative exponent means "divide by 10 this number of times" rather than "multiply by ten this number of times.So
1e2 = 1 x 10 x 10 = 100
1e1 = 1 x 10 = 10
1e0 = 1
1E-1 = 1/10 = 0.1
1e-2 = (1 /10) / 10 = 1 / (10 x 10) =0.01
