Integer division:
When both operands are integer data types, the resultant statement will be in integer division which means the outcome of the division will also be an integer data type. If there is a remainder, it must be ignored.
Example:
The example for the integer division is as follows:
double value;
value = 5 / 3;
In the above example, the outcome of the “5” by “3” is stored in the variable “value”. The value “1” is stored in the variable “value” because both “5” and “3” are integers, so the decimal part of the result must be truncated.
Floating-point division:
When both operands are floating-point or any one of the operand is a floating-point, the resultant statement will be in floating-point division, which means the outcome of the division will be a floating-point data type.
Example:
The example for the floating-point division is as follows:
double value;
value = 5.0 / 3;
In the above example, the result of the “5.0” by “3” is stored in the variable “value”. The value “1.6667” is stored in the variable “value”, because “5.0” is the floating-point data type and “3” is an integer data type, so the result has a floating-point value.

- The following variables have been initialized for you: int a; float f: double d: You have to cast the variable into different data types as follows: • Cast a as float to a variable x. • Cest fas an integer to a varieble y. • Cest d as flost to a variable z. Hint: You nae to initia ize the varlebles xy and z of proper data types. Note: The required code to take user input is already written for you. Similar to value asinput.

- HELP NEEDED ASAP! Language: JAVA The following code sequence is supposed to compare a float and a double with the same value and output that they are equal. What is wrong with the following code sequence? Why is it not showing the correct answer? Write your code to fix the problem. float piF = 3.141592653589793f; double piD = 3.141592653589793; if(piF == piD) System.out.println("piF and piD are equal"); else System.out.println("piF and piD are not equal");arrow_forwardExample: Enter an integer = 75 Smallest divisor is = 3arrow_forwardI need help tackling this program: Write a C++ console application that allows your user to enter the total rainfall for each of 12 months into an array of doubles. The program should validate user input by guarding against rainfall values that are less than zero. After all 12 entries have been made, the program should calculate and display the total rainfall for the year, the average monthly rainfall, and the months with the highest and lowest rainfall amounts.arrow_forward
- 2. Test Scores File: test_scores.py Write pseudocode for the main() part of a program that asks the user to enter 4 test scores between 0 and 100, then displays a JCU grade for each score and also the average test score. When you have written the pseudocode for main, implement your solution in Python code and test it with a range of meaningful data. Remember that we've done the JCU grades question before, so copy your function from that practical code file. Sample Output Score: 3 Score: 50.5 Score: 66 Score: 100 Score 3.0, which is N Score 50.5, which is P Score 66.0, which is C Score 100.0, which is HD The average score was 54.875 Enhancements When you have that working... We asked for 4 scores. Have a look at your code... did you use 4 as a numeric literal or a constant?Change 4 to 3... Did you have to change the program in more than one place?If so, then you've missed one of the things we've taught...As a strong guideline: if you need to use the same literal more than once, you…arrow_forwardCreate a program in C language that calculates the month's day from a given year and year's day.

- Asaparrow_forwardQuestion 2 A number in base 2 (binary) is a number such that each of its digits is O or 1. To convert from binary to decimal (base 10), the digits starting from the right are multiplied by powers of 2 (starting at 0) and added. For example, the value in decimal of 10011 is calculated as follows: Write a program that reads from the user a 5-digit integer representing a value in binary and displays its equivalent value in decimal. Note that if the user enters an integer which digits are other than 0 or 1, the program displays a message stating that the number is invalid. Sample Run 1: Enter a 5-digit integer made of Os and 1s: 10011 10011 in decimal is 19 Sample Run 2: Enter a 5-digit integer made of Os and ls: 13001 13001 is not validarrow_forwardRewrite the following statements using combined assignment operators: count = count + 1;arrow_forward
