Answer:
Expression for the above problem in python language:
userNum=int(input("Enter the value of user_Num")) #it is used to take input.
if(userNum>(-10)): #if statement
    print("The value of the userNum is greator")
elif(userNum==(-10)): #elif statement
    print("The value of the userNum is equal to -10")
else: #else statement.
    print("The value of the userNum is small")
Output:
- If the user input is (-10), it will print equal.
- If the user input 10, it will print greator message.
Explanation:
- The above program or expression is in python language, where the first line is used to render a message to the user take the input and store it into a userNUM variable.
- Then the second line is used to check the user num value to be greater with the help of if statement.
- Then the third statement is used to check the user num value to be equal with the help of elif statement.
- Then the else statement will execute when the if and the elif statement will not true.
 
        
             
        
        
        
Answer:Floating-point arithmetic is considered an esoteric subject by many people. This is rather surprising because floating-point is ubiquitous in computer systems. Almost every language has a floating-point datatype; computers from PCs to supercomputers have floating-point accelerators; most compilers will be called upon to compile floating-point algorithms from time to time; and virtually every operating system must respond to floating-point exceptions such as overflow. This paper presents a tutorial on those aspects of floating-point that have a direct impact on designers of computer systems. It begins with background on floating-point representation and rounding error, continues with a discussion of the IEEE floating-point standard, and concludes with numerous examples of how computer builders can better support floating-point.
