What is the role of the floating-point unit (FPU) in a CPU?

The role of the floating-point unit (FPU) in a CPU is to perform mathematical operations on floating-point numbers, which are numbers with decimal points or fractional parts. The FPU is responsible for executing complex arithmetic calculations, such as addition, subtraction, multiplication, and division, on these floating-point numbers with high precision and accuracy. It is specifically designed to handle the unique requirements of floating-point operations, including handling large numbers, maintaining precision, and handling special cases like infinity and NaN (Not a Number). The FPU greatly enhances the CPU's ability to perform scientific, engineering, and mathematical computations efficiently.
