Wanted a calculator for my Kindle. Loaded this and attempted to add up a restaurant bill, calculator constantly gave answers to several decimal places when adding more than two numbers together (also with multiplication). Example adding £3.12 + £5.37 you are OK, add another for example £1.19 and the answer will be provided (incorrectly) to 8 spurious decimal places and I don't just mean zeros. I have removed it and will find another. Do not bother.
That is what this is - a calculator - how do you rate it - it does sums - end of story - it does not deserve any points because it simply does what it says but I am in generous mood and it gets 3 points. End of sum
