Floating-point comparison

Floating-point comparison: Print Equal or Not equal.

Write an expression that will cause the following code to print “Equal” if the value of sensorReading is “close enough” to targetValue. Otherwise, print “Not equal”.

#include <stdio.h>
#include <math.h>

int main(void) {
 double targetValue;
 double sensorReading;

targetValue = 0.3333;
 sensorReading = 1.0/3.0;

if (fabs(sensorReading -targetValue)<0.0001) {
 printf("Equal\n");
 }
 else {
 printf("Not equal\n");
 }

return 0;
}
