A student asks: Dear Prof Patt, Can we use calculators of this exam? With the floating point stuff, it might be useful in saving some time. Thanks, <<name withheld to protect the student who wants his caculator>> Indeed, it might save you some time. However, for obvious reasons that I am not happy about, I will have to ask you to take longer to do the arithmetic without a calculator. Calculators will not be allowed in the exam. Use of a calculator will mean an automatic 0 on the exam. In the interest of saving you time, it is not necessary to work out the detailed arithmetic to the last detail. For example, if a calculation results in a value containing fractions, leaving the result in fractional form will receive full credit. For example, suppose the answer to a floating point question is 1.0011 x 2^(-1), it would be enough to show the answer as 19/32, which is 1/2 + 1/16 + 1/32. You do not have to do the division. OK? Good luck tomorrow. Yale Patt
