Here 3.55 is stored as a floating point number after converting it to
mantisa and exponent. when you print the hex value of u.l_e you will get the
floating point number in below format. and %ld will print the decimal value
for it.
Hope this is clear.

*Format*

SEEE

EMMM





*Binary*

1101

01001000

Re: [algogeeks] union- c

[Anurag Sharma]

Check the floating point representation(IEEE 754 format) in variables. There
are specific number of bits in a float variable to represent exponent,
mantissa etc.

If you are not able to print the long int and that's the prob, you can use
%ld instead of %d
