Actually, In C float and double has only two differences. one is size. and another one is storage in memory.
float has only single precision. But double has double precision.
So, In your code you are trying to differentiate this. But it gives output as hello because it is equal.
double 0 is equal to float 0.
If you want differentiate float and double try this code.
1 2 3 4 5 6 7 8 9 10 11 | <br /> #include<stdio.h><br /> main()<br /> {<br /> long double a =0.0;<br /> if(a>=(float)0.0)<br /> printf("hi");<br /> else<br /> printf("hello");<br /> }<br /> |
It will prints hi.
1 2 3 4 5 6 7 8 9 10 11 | <br /> #include<stdio.h><br /> main()<br /> {<br /> long double a =0.1;<br /> if(a>=(float)0.1)<br /> printf("hi");<br /> else<br /> printf("hello");<br /> }<br /> |
It will prints hello.
I think now you can get the difference.
