Thread: Unexpected behaviour with float

Please consider the following code

Code:

void main()
{
  float a = 0.7;
  if(a <= 0.7)
     printf("Less or equal");
  else
    printf("Greater");
}

Surprisingly (for me) it printed

Code:

Greater

However, when I change the initialization expression to the following

Code:

float a = 0.8;

and change the if condition to

Code:

  if(a <= 0.8)

it prints the expected output:

Code:

Less or equal

Kindly explain. Thank you in advance.
