1.   The _________ is that part of the computer that actually performs arithmetic and logical operations on data.

2.   Extending the range of numbers that can be expressed by increasing the bit length is referred to as __________.

3.   _________ representation is when the radix point is fixed and assumed to be to the right of the rightmost digit.

4.   If two numbers are added, and they are both positive or both negative, then _________ occurs if and only if the result has the opposite sign.

5.   “To subtract one number from another, take the twos complement of the subtrahend and add it to the minuend” is the _________ rule.

6.   When the divisor is able to divide the number, a 1 is placed in the quotient and the divisor is subtracted from the partial dividend; the result is referred to as a ________.

7.   A __________ is one in which the most significant digit of the significand is nonzero.

8.   _________ occurs when an arithmetic operation results in an absolute value greater than can be expressed with an exponent of 128.

9.   The most important floating-point representation is defined in IEEE Standard _________, adopted in 1985 and revised in 2008.

10.   __________ format is a fully specified, fixed-length binary encoding that allows data interchange between different platforms and that can be used for storage.

11.   _________ format covers five floating-point representations, three binary and two decimal, whose encodings are specified by the standard, and which can be used for arithmetic.

12.   IEEE 754-2008 defines an __________ format as a format with a precision and range that are defined under user control.

13.    The register contains additional bits, called __________, which are used to pad out the right end of the significand with 0s.

14.     __________ is when the result is put back into the floating-point format and the extra bits must be eliminated in such a way as to produce a result that is close to the exact result.

15.    The use of subnormal numbers is referred to as _________ underflow.
