Today's Free App of the Day is Advanced Calculator
Originally $0.99

Another calculator! This is probably the least interesting of the ones we've had lately, but if you mostly just want to be able to add stuff up or calculate a tip, it's great--big buttons. You can access some advanced functions by tapping on the ADV button. Return by tapping the BAS button. I couldn't find any memory to save values to. No instructions, but it's mostly self explanatory, though info about some of the advanced functions might be nice. Two that people might not know are the ! (factorial) and the ceil function. ! is used with a number before it and gives the product of that number and all of the integers less than it. So 4! is 4*3*2*1; 5! is 5*4*3*2*1, etc. And ceil() gives the first whole number larger than the result in the parenthesis. So, if you want to round up to whole dollars, say, you can enter ceil(45.3x26.9), press the equal sign and get 1219. Biggest plus is the size of the buttons and easy to read display if you need them. Biggest negatives for me were no history or tape function and no memory to store numbers in. I'd give it 3 stars.

8 of 10 reviews are four stars and above.
