[edit] Picture

Someone gotta be kidding me by saying that that picture is from XP. Come on, anyone can see that it's Windows 95 or something...to make up for it, I'll add a shot of the newest version available: the Windows Vista version. Oh!..... Shandristhe azylean 19:45, 2 July 2006 (UTC)

Well, not everybody uses XP with the fancy blue bars and all. I uploaded a new version, though. --Merovingian {T C @} 21:22, 2 July 2006 (UTC)

[edit] pi

How many digits of pi does the calculator store? I once clicked pi, then clicked copy, then clicked the button to subtract, then clicked paste, and finally multiplied the result of that by 10^31, and then I got the next thirty-something digits of pi, and then repeated, and using this method figured out that it had stored at least the first 200 digits of pi. I wonder how whether every microsoft computer has the first 1000 digits of pi stored in some obscure file, or if it was generating them on demand using some algorithm. Any ideas? And the same holds true with e, obtainable by just typing 1, then inv, then ln. 209.6.229.150 23:36, 18 December 2006 (UTC)


It's not accurate to that many digits. Floating point number are easily eroded in computation because they are not easily represented in binary. (read more Floating point) But here is a crude test:

Microsoft Pi:

Pi per Wikipedia (50 digits): 
3.14159265358979323846264338327950288419716939937510


Wow, for a second I thought Microsoft had done something right! 209.6.229.150 00:51, 13 January 2007 (UTC)

Well that's a silly comment, microsoft used a very precise pi more precise than most data types support, in fact I think it probably is 32 significant digits guaranteed so that would make it a decimal variable (a double precision double)83.226.47.248 20:38, 30 January 2007 (UTC)

[edit] Pasted Text

I lack a pre-Windows XP version of Calculator to test this functionality on older versions, or I might have just replaced the existing trivia section. In the Windows XP version the effect of pasted text is different than noted in trivia. Can anyone confirm this on other versions?

For one, it doesn't matter if the pasted text is on one or several lines. Hard returns are ignored, although tabs seem to effectively stop input at that point.

While order of operation seems to be preserved (3 + 5 * 2 equals 13, not 16), it seems that otherwise the effect is essentially identical to typing the same characters. One isn't limited to the basic four functions, but can use the keyboard equivalents of most other buttons. These can be found in the Calculator help file's "Using keyboard equivalents of Calculator buttons" or by right clicking on such a button and selecting "What's this?"

For example, 4i@= is like clicking 4, checking Inv (inverse), and clicking x^2, producing 2 (the square root of 4).

This functionality can be useful when parenthesis are involved, such as for fractions. However, the written out expressions can still become long and unwieldy. For example, (((3/4)+(16/9))/(1/3))y(1+(7/8)) for three quarters plus sixteen ninths, the result divided by a third, and that result raised to the one and seven eighths power. —The preceding unsigned comment was added by 70.41.110.107 (talk) 01:11, 23 March 2007 (UTC).

[edit] Arbitrary-precision vs IEEE

The Calculator in Windows 2000 and later Windows NT-based versions uses an arbitrary-precision arithmetic library, replacing the standard IEEE floating point library.

I believe the "arbitrary-precision arithmetic library" was already used in Win98 SE. I still have this version and I can calculate as high as 2 ^ 65536 in full precision, while the floating point calculator (double precision) in QBasic has a limit of 2 ^ 1024. What's the limit of MS Calculator anyway?--Tai Ferret (talk) 19:55, 25 November 2007 (UTC)
