/*
This program uses several functions from the math.h library:

    abs: calculates the absolute value of a number
    ceil: rounds up a float to the nearest integer
    floor: rounds down a float to the nearest integer
    round: rounds a float to the nearest integer
    pow: calculates the power of a number (e.g., 2 raised to the power of 3)
    sqrt: calculates the square root of a number

The program demonstrates the usage of these functions with example values. The
output will show the result of each function call.
