Here is the example problem slide I am working with:
I understand how to get the exponent, its just 2+128=130-127=3
I understand the first bit is the sign bit for positive or negative.
I just get lost with the mantissa. I know each mantissa has to have a 1 before the decimal, but I'm unsure where the .75 came from. 1100000000000000000000 isn't 75 in decimal I mean right?
How do I calculate the mantissa with floating point numbers in binary?
