1 First Midterm TestIndexup to index

Calculators are not permitted during the first midterm test. You will benefit from knowing the powers of two from 2^(-4) to 2^16 and the decimal and binary values of the hexadecimal digits from zero to fifteen. Of course you can work them out; however, having at least some of them memorized will make things go faster for you on the test. (Remember that hexadecimal “A” = decimal 10 = binary 1010.)

###Overflow causes rocket to self-destruct### - http://www.around.com/ariane.html - http://en.wikipedia.org/wiki/Ariane_5_Flight_501

“a data conversion from a 64-bit floating point to 16-bit signed integer value caused a hardware exception (more specifically, an arithmetic overflow, as the floating point number had a value too large to be represented by a 16-bit signed integer)”
