Error while comparing Float variable

[cijothomas]

Dear friends,
Please take a look at the following code. Its storing .7 to b and comparing b with .7 . But getting just the opposite of expected result!!

Please explain!

(Three is expected o/p but we get two when run)

#include<stdio.h>
int main(int argc,char **argv)
{
 float a=0.5,b=0.7;
 if(b<0.7)
 {
	 
	if(a<0.5)
	 {
   printf("\nONe");
	}
     else
	 {
   printf("\nTwo");
	 }
 }
 else
 {
  printf("\nThree");
 }
 return 0;
}
