Integers and floating points are separated by the presence or absence of a decimal point. For instance, 5 is an integer; 5.42 is a floating-point number.; Complex numbers are written in the form, x + yj, where x is the real part and y is the imaginary part. We can use the type() function to know which class a variable or a value belongs to.. Let's see an example,
