Sign=positive
01101010110101001111111 bin
Decimal point added to the first position of the mantissa
01101010110101001111111
Leading 1 in front of the decimal point
1. 01101010110101001111111
Taking the exponent into account (=5)
101101. 010110101001111111
to the left of the decimal point: 101101 bin = 25+ 23+ 22+20 =
45 dec.
To the right of the decimal point: 010110101001111111 bin =
2-2 + 2-4 + 2-5 + 2-7 + 2-9 + 2-12 + 2-13 + 2-14 + 2-15 + 2-16 + 2-17 +
2-18 = 0.3540001 dec
