FP, the conversion to decimal is a hard process when the exponent is big.
Try for example to convert 1.01001100110b * 10b^11101010b (b indicates that
the number is a binary number)
Let's see, that means 1.01001100110 with decimal point shifted right 234
decimal places. That means 101001100110 with 223 more zeroes. Hmmm, that
means 2662*2^223, which equals 3.5883689013977501566701797080823*10^70. Oh
wait, that's too much significance...
