Fractional Part Function Solved Examples
Example 1: Calculate the fractional part of 5.63 using the Fractional Part Function.
Solution:
Fractional Part Function is given by:
{x} = x – ⌊x⌋
For x = 5.63:
{5.63} = 5.63 – ⌊5.63⌋
Now, find the greatest integer less than or equal to 5.63:
⌊5.63⌋= 5
Substitute this back into the formula:
{5.63} = 5.63 – 5
{5.63} = 0.63
So, the fractional part of 5.63 is 0.63.
Example 2: If y = { -3.8 }, determine the value of y.
Solution:
Fractional Part Function is given by:
{x} = x – ⌊x⌋
For (x = -3.8):
{-3.8} = -3.8 – ⌊-3.8⌋
Find the greatest integer less than or equal to -3.8:
⌊-3.8⌋=-4
Substitute this back into the formula:
{-3.8} = -3.8 – (-4)
{-3.8} = -3.8 + 4
{-3.8} = 0.2
So, if y = { -3.8 }, then y = 0.2
Fractional Part Function
Fractional Part Function, often denoted as {x}, represents the decimal part of a real number x after removing its integer part. In simpler terms, it captures the fractional portion of a number, excluding the whole number component. The fractional part function is particularly useful in various mathematical contexts, such as number theory, analysis, and computer science, where understanding the non-integer portion of a number is essential.
In this article, we will learn about the various concepts related to the fractional part function, like the meaning and definition of the fractional part function, properties of the fractional part function, its formula, application, graph, and solved examples for better understanding.
