Why it print command working?

Question

#include<stdio.h>
int main(){

float a=0.7;
if(0.7>a)
printf("Hi" );
return 0;
}

Answer 1

because of decimal floating point storage innacurracy and default literal stored as double:

try:

if (0.7f>a)

instead, or log value of 0.7-a in exponent notation:

printf("Hi %e",0.7-a);

Answer 2

Slick no, the result of 0.7>a is true, because 0.7 is double and a is float ^^

Answer 3

Kaptan Kaan Yıldırım you can also log 0.7f-a to see the difference:

printf("Hi %e",0.7f-a);

Answer 4

Because .7 is not greater than .7, they are equal.

test: if a == 0.7
