#include <stdio.h> int main() { float a=0.7; if(0.7>a) printf("hi"); else printf("hello"); }

Question

Why the output is hi

Answer 1

Rohit Ahuja
It's because a is 0.69999999998 in it's floating representation.

And normal 0.7 is an double precision value, So the comparison between float and double leads to type promotion and in that case a is less than 0.7 which is double. So the output will be printed as hi

this thread will give you some detailed answer about the precision value types
