Comparing Floating Point Variable With a Value In C Programming

In this video tutorial lets see how we can compare a floating point variable with a constant value, and lets see the result.

The Problem
If you assign 0.7 to a floating point variable num and then inside if condition you check if num == 0.7, it returns false. Because here variable num is of data type float and the constant value 0.7 is considered as double type data.

Better to never compare floating point numbers utilizing the == operator, just check if the numbers are "close enough" by obtaining their difference and checking if it is smaller than an 'epsilon'.
