Assuming a three-bit exponent field and a four-bit significand, write the bit pattern for the following decimal values:

(a) -12.5 (b) 13.0 (c) 0.43 (d) 0.1015625

Here are the answers I got for each:

(a) 1 110 1010

(b) 1 110 1010

(c) 0 001 1011

(d) 0 000 1101

I don't know how to check if these are correct. Could someone help me please?
