THINGS TO NOTICE
The answer will always have eight bits.Padding is done before inverting or adding one.
If the decimal number is positive, then all three formats give the same bit pattern, and the left-most bit of the answer will be zero.
If the decimal number is negative, then the three formats will give different bit patterns, but in each case the left-most bit of the answer will be one.
THINGS TO TRY
Set slow-motion to 0.5, select random format, click setup, and then click go.Set the format to a type you wish to drill, and set random-format off. Click setup. Work each step by hand, and then click the step button to check your answer.
