Use this simple program to practice floating point notation using an
ABBBBCDDD format (I know, that's nine bits, but that's how we did it in lecture,
exact format doesn't really matter) A represents the sign of the
mantissa (1 is negative) B represents the mantissa value, C represents
sign of the exponent and D is the exponent. Have the computer
generate a random binary or decimal value for you by pressing the
appropriate button. Work out your answer on paper, then enter it in
the other box. Hit the "Check answer" button to check your work.
