Approximate pi to 24 digits via keyboard

[Thomas Klemm]

Isn't the result given by the HP-41C or HP-15C more appropriate than returning 12 digits like the HP-48G? Since we can't enter more than 12 digits why should the calculator assume that next 12 digits are all 0? But that's exactly what happens:

Code:

  3.14159265358979323846264
- 3.14159265358000000000000

  0.00000000000979323846264

In the worst case the next 12 digits are all 9 thus we're very close to \(3.14159265359\) and end up with \(-2.06761537357 × 10^{-13}\) instead.

It's interesting that they did this but honestly I don't see an application where these additional digits are useful.

Cheers
