How to check if number is divisible by a certain number?

division

I am using AndEngine to add sprites to the screen and come across using the movemodifier method.

I have two integers MaxDuration and MinDuration;

What i want to do is when the user gets to a score of a certain increment.

Like for example.. when the user gets to 20(the integer changes) when the user gets to 40(the integer changes). So basically count by 20 and every time the score meets a number divisible by 20 the integer's change. I hope this makes sense.

Is there any method or way to do this? I have an UpdateTime handler that can check the score just about every second.

Any ideas?

How do you identify a number if it is divisible by 3?

A number is divisible by 3 if sum of its digits is divisible by 3. Illustration: For example n = 1332 Sum of digits = 1 + 3 + 3 + 2 = 9 Since sum is divisible by 3, answer is Yes.

How do you check if a number is divisible by a number in Java?

If the sum of the digits of a number is divisible by 9, then the number is divisible by 9. Some examples of numbers divisible by 9 are as follows. The number 51984 is divisible by 9 because the sum of its digits (5+ 1 + 9 + 8 + 4 = 27) is divisible by 9.

What is the rule of test of divisibility?

A divisibility test is an easy way to identify whether the given number is divided by a fixed divisor without actually performing the division process. If a number is completely divided by another number, then the quotient should be a whole number and the remainder should be zero.

How to check if a number is divisible by 2?

To check a number is divisible by 2 or not. As every alternate number is divisible by 2 and rest are not. So in the above example all the FALSE values are odd numbers. Now we check if the number is divisible by 2 or not. Copy and paste the formula to all rest values to check divisibility by 2

What is the divisibility test for even numbers?

A number is even if it ends in 0, 2, 4, 6, or 8. Examples of numbers that are even and therefore pass this divisibility test. Since the last digit is a 2, the entire number, 12, is an even number and therefore divisible by 2. Since the last digit is an 8, this is an an even number and therefore divisible by 2.

What is the last digit of 4 divisible by 2?

Since the last digit is 0, this is an an even number and therefore divisible by 2. Since the last digit is a 4, this is an even number and therefore divisible by 2. Check if any number is divisible by two.

How do you know if a number is divisible in Python?

When working with numbers in Python, it can be useful to know if the numbers you are working with are divisible by certain numbers. We can use the Python built in remainder operator %to get the remainder of a number after division. If the remainder after division is 0, then the number is divisible by the number you divided by.

n % x == 0 

Means that n can be divided by x. So... for instance, in your case:

boolean isDivisibleBy20 = number % 20 == 0; 

Also, if you want to check whether a number is even or odd (whether it is divisible by 2 or not), you can use a bitwise operator:

boolean even = (number & 1) == 0; boolean odd  = (number & 1) != 0;
