The C programming language defines two constants, MIN_INT and MAX_INT, corresponding to the lower and upper bounds of the range of values representable by a signed integer.

Assuming signed integers are stored using 11 bits in 2's complement form, what would be the value of MIN_INT? Express your answer in decimal (base 10).

A modified IEEE-754 floating-point representation uses 9 bits for the exponent and 6 bits for the fractional mantissa. The exponent is expressed in binary, excess-k. What is an appropriate value for k?

An IEEE-754 floating-point representation uses 4 bits for the fractional mantissa and 4 bits for the exponent (represented in excess-k). What is the largest positive value that can be represented? Express your answer in decimal (base 10).
