Yeah bignums don't really help with transcendental functions, whose reported values are almost always irrational.
We could detect cases like that, especially the .9999,,, ones, and round the displayed result, without losing precision internally. It's on my ever-growing list of things to convince Jens to do someday.
Because I'm old and can't always see the difference between commas and periouds, which whoever designed the typewriter keyboard layout foolishly placed next to each other.
Me too. I never officially learned touch-typing and I use all the wrong fingers (mostly just my index fingers!), but after many years of typing I've gotten to where I can do pretty well looking at the screen instead of at the keyboard.
I now use my index fingers mostly, though I sometimes use my middle fingers, (usually for the backspace and, it seems, O.) as well as my pinky fingers for Shift and Ctrl, and my thumbs for spaces. (Usually my right thumb.)
