Answer :

I hate U

Explanation:

For floating point numbers (float, double, long
double) the values cannot be predicted exactly. Depending on
the number of bytes, the precession with of the value
represented varies. Float takes 4 bytes and long double
takes 10 bytes. So float stores 0.9 with less precision than
long double.

Rule of Thumb:

Never compare or at-least be cautious when using
floating point numbers with relational operators (== , >, <,
<=, >=,!= ) .
