3 cards from this section. Quick, good the night before a test.
What is the function of the sign bit in floating-point representation?
Think about how we denote positive or negative numbers.
What does the significand represent?
What part of a number contains the important values?
What part of the floating-point representation determines the number's sign?
What indicates positive or negative signs in math?
True or False: The significand always includes a decimal point.
Think about how we write numbers without showing the decimal.
Convert the decimal number -5.75 into a 32-bit IEEE 754 representation.
Start by converting to binary and then normalize.
Given the biased exponent of 140 in IEEE 754, what is the corresponding actual exponent? If the significand is 01000000000000000000000, determine the floating-point number.
Remember to subtract the bias to find the actual exponent.
