82. (H446) SLR13 – 1.4 Floating point arithmetic

What is the first step in adding two normalized floating point numbers?

• Perform binary addition.

• Align the binary points.

• Determine the exponent for each number.

• Pad empty columns with zeros.

How do you handle empty columns when aligning two binary numbers for addition?

• Ignore them.

• Leave them blank.

• Fill them with ones.

• Pad them with zeros.

What is the significance of the exponent in floating point arithmetic?

• It indicates the number of bits in the mantissa.

• It specifies the precision of the calculation.

• It determines the base of the number system.

• It dictates the position of the binary point.

In the context of binary addition, what does 'carrying' mean?

• Moving a bit to the next higher column.

• Swapping a zero for a one.

• Ignoring overflow bits.

• Adding two zeros to produce a one.

What do you do if the result of a floating point addition cannot be stored in the given format?

• Round the result.

• Increase the number of bits.

• Accept the loss of precision.

• Only store the integer part.

What does normalizing a floating point number involve?

• Adjusting the binary point to a standard position.

• Rounding it to the nearest whole number.

• Converting it to an integer.

• Splitting it into exponent and mantissa.

How is the exponent represented in a normalized floating point number?

• It is not explicitly represented

• In decimal form

• As a binary number

• Using two's complement

What limitation of floating point formats is highlighted in the video?

• Inability to represent negative numbers

• Inability to store certain results due to bit limitations

• Inability to represent very large numbers

• Inability to perform subtraction

What is the result of the addition example with two more normalized floating point numbers?

• 6.375

• 0

• -2

• 3.125

What does a negative exponent indicate in floating point arithmetic?

• The number is negative.

• The binary point moves to the left.

• The number is an integer.

• The binary point moves to the right.
