Division Without Remainder: Techniques to Simplify Your Math
For many students, math can be a daunting subject, especially when it comes to division. While division is an essential mathematical operation, it can sometimes involve cumbersome calculations and even leave a remainder.
In this article, we will introduce you to some techniques that simplify division without the need for remainders, including floor division, math.floor(), math.ceil(), round(), int(), and math.trunc() methods. Using the Floor Division Operator //
The floor division operator // is a widely used method of dividing two integers and returning the quotient (result) as an integer.
It is denoted by two forward slashes (//). Lets consider the following example: 14 // 3 = 4.
What this equation tells us is that when we divide 14 by 3, we get 4, and any remainders are ignored. Floor division operator // helps to remove the remainder, making it a useful tool for many mathematical applications.
Using the math.floor() Method
In many scenarios, you may want to obtain the largest integer that is less than or equal to a given number. In such cases, the math.floor() method comes in handy.
The function takes a float number as input and returns the largest integer value that is less than or equal to it. We can use this function to get the floor value of a value returned by an expression or a calculation.
For example, math.floor(9.8) will return 9 as the largest integer value that is less than or equal to 9.8.
Using the math.ceil() Method
The math.ceil() method is the opposite of math.floor(). It provides the smallest integer that is greater than or equal to a given number.
This function is useful when you want to round up to the nearest integer, as it enables you to obtain the next integer that is closest to the given value. So, math.ceil(9.2) will return 10, the smallest integer that is greater than or equal to 9.2.
Using the Round() Function
The round() function helps to return the nearest integer to a given decimal number. It is applicable when you need to round up to the nearest integer.
The function takes either one or two arguments. If no second argument is provided, the function returns the closest integer to the decimal number.
So, round(7.8) will return 8. If a second argument is provided, the round() function will round the decimal number to the number of decimal places specified in the second argument.
For instance, round(6.535, 2) will return 6.54, which is the nearest number to 6.535, rounded to two decimal places.
Using the int() Class
The int() command is another method that helps remove the fractional part of a given decimal value. When using this method, the decimal number is truncated, and the integer part remains.
For instance, int(5.67) will return 5. Using the math.trunc() Method
Sometimes you may need a quick way to get the integer value of a given float number.
The math.trunc() method helps to remove the fractional part of a given decimal value and return the integer part. It is similar to the int() method, but it’s much faster and doesn’t have to deal with the built-in error checking.
For example, math.trunc(4.56) will return 4 as the integer value of 4.56.
