MGMT 1030 Chapter 8 Notes – Summary
Introduction
• Since the number is already normalized (no leading zeros), there is no adjustment
required.
• There are seven digits, so we drop the two least significant digits, and the final
exponential representation is 0.24680 × 103 5.
• The exponent is 3, which in excess-50 notation is represented as 53.
• If e represet a + sig ith the digit , ad a – sig ith the digit
• This choice is totally arbitrary, but we needed to select some digits since the sign itself
cannot be stored
• The final stored result becomes the sign 05324680 the mantissa excess-50 exponent.
• Assume that the number to be converted is × − .
• The number is already in exponential form.
• We must shift the decimal to the left four places, so the number becomes 0.1255 × 10+1
• The positie expoet results fro addig to the origial − expoet.
• The number is normalized, so no additional adjustment is required.
• A zero is added to provide five digits of precision.
• The final result in exponential form is 0.12550 × 101 5.
• The exponent in excess-50 notation becomes 51, and the result in word format is
05112550
• Assume that the uer to e oerted is −. .
• Coertig to expoetial otatio, e hae −. × .
• The decimal point is already in its correct position, so no modification is necessary.
• Noralizig, the uer eoes −. × − .
• And the fial expoetial result, −. × − .
• In our word format, this becomes 54475000.
• Although the technique is simple and straightforward, it will still require some practice
for you to feel comfortable with it.
