The built-in Calculator app on the iPhone and iPod touch can be a handy way to quickly work out quick calculations, and the good news is that if you’re trying to calculate something that needs to go into an e-mail, text message, or elsewhere on your iPhone, the iOS clipboard is fully supported, although it may not be obvious. Simply tap and hold on the number and the usual context menu will pop up with a Copy option displayed. There’s also a paste option here too, so if you’ve got a number from an e-mail or message that needs to be entered into your calculation, you can simply paste it here rather than having to memorize it and key it in manually.
