in reply to Adding really big numbers

What lib are you using? How are you declaring accuracy and precision? Maybe this'll help:
#!/usr/bin/perl -l BEGIN { $| = 1; $^W = 1; } use strict; use warnings; use bignum lib => 'FastCalc'; use Memoize; memoize('really_big'); really_big(); sub really_big { bignum->accuracy(15); bignum->precision(15); my $big_number = 3710728753390210279879799822083759024651013574025 +0 + 46376937677490009712648124896970078050417018260538; print $big_number; }

[Corion]: Talking about it, the top should be fairly visible in the situations I've experienced at least. The top is uncomfortable for people in the first three rows, but that's life ;)
[ambrus]: The pillars are there because this is in the 6th floor of building R of BME, which is an attic that was built in after the original building, which is also why the elevator doesn't go that high and the windows are tiny.
[Corion]: ambrus: Hehe ;) Yeah - such real life stuff is far more inconveniencing than wasting display area due to screen ratio problems :)
[ambrus]: Corion: yes, it's a bit tricky. you can try to adjust the slides live to cover only a part of the screen, but it's still hard.
[ambrus]: Corion: two very hard things about presentations I should try to work on if I have twenty times as much free time as in real life are:
[Corion]: That's why I like HTML - it makes it relatively easy to resize stuff. Resizing with Powerpoint is much harder, or at least, I remember it being that way
[ambrus]: (a) good sans serif fonts optimized for slides in a projector with coverage of the symbols needed for mathematical formulas in a sans serif font matching the text font well, and
