There are 3 things.
- Sign bit
- Exponent byte
- Mantissa
Sign bit
0 is positive, 1 is negative.
Exponent byte
- Remove meaningless zeros
- Move decimal n places such that its right behind the first 1 in the number
- count the number n places which you moved
- Add N to 132
- Convert this number to binary
- Thats the answer for you
Mantissa
- Write the bits as is after the decimal
- Add enough trailing zeros after the number ends
