Data Representation - Floating Point Numbers
Today we’re going to learn about floating-point numbers. Floating-point numbers are used to approximate real numbers. The representation of floating-point number had to made trade-offs between ranges and precision. Terminologies The terminologies of floating-point number is coming from the scientific notation, where It would be algebraically ideal if the set of floating-point numbers can be closed under all floating-point
