floats in c++ are stored as they are in computers generally, it has bits dedicated to the sign, exponent and mantissa. read more here: https://en.m.wikipedia.org/wiki/IEEE_754

The problem is that doing maths with floats is inexact, so you need to do "inexact comparison" too. It really depends on your application though. https://code.sololearn.com/cfpN6pnAjVNk/?ref=app

To store the float c++ followed IEEE-745 standard. Please Google it read more about IEEE standard. you can compare two float using if condition. float ft=5.35; if (5.35f == ft) cout<<"Match found"<<endl;
