$10^11$

The following site lists countries by their number format system

www.codeproject.com/Articles/78175/International-Number-Formats

(The list is recent and comprehensive)

These formats are the most common

1,234.56

1.234,56

1'234.56

1 234,56

These formats are rare, used by one or two countries.

1,234/56

1 234-56

1 234.56

---- Note: Some multicultural countries use more than one format. It is probable that cross-cultural communications are sent in the recipient’s format, for clarity. Computer communications may automatically convert to recipient’s format via computer settings. ~~D~~

 $10^11$ it's a syntax error.

The correct variant is   $10^11

$10^11   =   100.000.000.000

yeah it is $100 000 000 000 but what is up with all the decimal points in Anonymous' anwer

Some cultures interchange the use of commas (,) and decimals (.)

100.000.000.000 = 100,000,000,000

0,02580 = 0.02580

The calculator on this site uses either convention depending on context. Entering the above or similar formatted numbers will yield correct results.

-----

Note also, with the use of two specifically spaced commas the calculator will display results in scientific notation.

For example: enter 2^199 and the calculator will display 60 decimal digits; choose an arbitrary position to the right of the first digit and enter a comma, move three more to the right and enter another comma, then click the “=” (or press enter). The display will convert to (standard) scientific notation, with up to a 16-digit mantissa following the decimal point and its preceding value. (In this example, the value is 8.0346902212949514e59)

The same applies to extremely small values. For example (2^199 )^-1. In this case, choose an arbitrary place to the right of the first value after the decimal point, and place the second coma three values to the right. (In this example, the value is 1.245e-60).

The short version is: two comas, three values apart. The above also works with negative numbers.

This computer generated “calculator” is a brilliant peace of programming. At one time, this calculator would generate results with atomic accuracy at galactic distances (plus or minus the bugs and limitations of log and trig functions). Now, most functions (except for exponential) are rounded to 16 digits. This is more like galactic accuracy at atomic distances, but it keeps the FLOP load down when tens of thousands of users are seeking solutions.

Another feature of this calculator are “Easter eggs” hidden in the subs. Entering certain string combinations would generate German phrases. There were at least three, but none of them work anymore. The best were, “Speichern Sie diese Scheiße für die Vögel,” and “Führen Sie Sie gefickt bis, ja wissen.”

Here is a brilliant peace of programming and a great sense of humor.

Hi Bioschip, DavidQD and anonymous,

I have seen commas used as decimal points (this is quite common - I think my students that used to do it were from African nations, maybe Sierra Leone? Not sure) but I have never seen periods (dots) used to separate place value!   

Which countries do that ?  Maybe DavidQD or our anonymous person could tell me?

Thanks David.  

There ARE a lot of them.
