 Hi, let's talk about that how to format floating numbers to string. In this example I will use peak constant, so I am going to import mat module and as you know peak constant in mat is approximately 3.14 and so on, it has infinitive number of decimals. Let's say that we want to make a string, let's call it p string in which we're going to put the value of our constant. If you want to format your string with float point number, you can add percent sign and letter f, which represents that we want to change occurrence of this percent and letter f with a floating point number. So we have this string in which we want to change this occurrence of percent sign and letter f with this number, which is defined as peak constant, so we're going to call mat module and constant p and we're going to use percent sign between them, so this occurrence of this sign will be changed with mathematical constant p. Let's press enter and let's print our constant and as you can see you will get that p equals to 3.141593 and so on. What will happen if we want to have just two decimals? We're going to make another string, let's say p string 1 with same text and now we want to have here our floating point number constant p with just two decimal numbers, so we're going to put point and number 2, which will represent that after the point we want to have just two digits and again we want to format our float number, so we're going to use again letter f and let's call again our math p constant and let's bind them with percent sign. Let's press enter and let's print our new string and as you can see now our string is formatted with two decimals. That's all in this lesson, thanks for watching, bye bye.
