hi all, i've been making some probability programs for my prob+stats class, and i want to make them as accurate as possible. is there any way that a TI-84 can round using significant figures? for example, if i used the round() command on the number 1.0873, and rounded it to two decimal places, the answer would be 1.09. if that same number were rounded using sig figs, the answer would be 1.087. that's what i need. does anyone know how to do it?
I still would not turn my printers off, the energy on standby is minimal, i like them ready to be used. I can kind of understand your reason for disabling the spooler, never done it myself, seems like a waste of time, anyway I use a Mac for most things these days. The one thing I must get in the habit of doing is turning the scanner off from the mains, i have a smart plug that I will stick on it, the scanner have a external PSU and still pull a fair bit of energy, even when not in use and I don't use it that often.
I can understand turning the printers off, maybe, but the energy they use while on standby is very small, my Brother LED printer, uses less than a watt in deep sleep, the same as the Epson printer. So compared to other stuff they use nothing. I don't use the printers as much as i used to, I want to use the Epson more, which is an ink-jet, that is why I got it to do photos and crafting stuff.
Turning a laser off is fine, mine will go to a off state, it then uses even less energy. The Brother while it is a LED printer, it works the same way as a Laser printer, but with LEDs instead of a laser.
as i said, i don;t use the printers as much asi used to, but I like the idea that they are there when I need them.
