Floating-Point Numbers
Numbers with decimal parts are called floating-point numbers. Like integers, floating-point numbers can be both positive and negative.
For example, 32.9, -56.5, 9.0, etc.
Important! Numbers like
9, 5, 28, etc. are treated as integers by C. However, C treats 9.0, 5.0, 28.0, etc. as floating-point numbers because we have put a decimal point in these numbers.
