Fractional part function properties

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 fractional part function properties to the fractional part function, like the meaning and definition of the fractional part function, properties of the fractional part function, fractional part function properties, its formula, application, graph, and solved examples for better understanding. It represents the portion of x that comes after the decimal point.

Fractional part function is a special type of function in algebra which is defined as the difference of a real number and its integral value. As the name suggests, the fractional part function gives the proper fraction of a number that remains after subtracting its integral value from it, and hence the range of the function is [0, 1. The value of the fractional part function is always a fraction less than 1. In this article, we will understand the properties of the fractional part function, its domain and range, its graph, and its formula. We will also solve a few examples based on the fractional part function for a better understanding of the concept. The fractional part function is a function that gives the fractional part of x by subtracting the greatest integer less than x from x, where x is a real number.

Fractional part function properties

The function giving the fractional noninteger part of a real number. The symbol is sometimes used instead of Graham et al. Unfortunately, there is no universal agreement on the meaning of for and there are two common definitions. Let be the floor function , then the Wolfram Language command FractionalPart [ x ] is defined as. This definition has the benefit that , where is the integer part of. Although Spanier and Oldham use the same definition as the Wolfram Language , they mention the formula only very briefly and then say it will not be used further. Graham et al. The fractional part function can also be extended to the complex plane as. The possibly scaled periodic waveform corresponding to the latter definition is known as the sawtooth wave. The fractional part of , illustrated above, has the interesting analytic integrals. The plot above shows the fractional parts of for , showing characteristic gaps Trott , p. A consequence of Weyl's criterion is that the sequence is dense and equidistributed in the interval for irrational , where , 2, Finch Weisstein, Eric W. Fractional Part Download Wolfram Notebook.

Then, the fractional part can be formulated as a difference :. For a positive number written in a conventional positional numeral system such as binary or decimal , its fractional part hence corresponds to the digits appearing after the radix point. The result is a real number in the half-open interval [0, 1. However, in case of negative numbers, there are various conflicting ways to extend the fractional part function to them: It is either defined in the same way as for positive numbers, i. These two definitions of fractional-part function also provide idempotence. Every real number can be essentially uniquely represented as a continued fraction , namely as the sum of its integer part and the reciprocal of its fractional part which is written as the sum of its integer part and the reciprocal of its fractional part, and so on.

It represents the portion of x that comes after the decimal point. Formally, for any real number x, the fractional part is given by the equation:. The fractional part function always yields a value between 0 inclusive and 1 exclusive.

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. Oxford Dictionaries. The fractional part function subtracts the integer part from the original number x, leaving only the decimal part or the fractional component. Campus Experiences. Yes, the Fractional Part Function is periodic with a period of 1. The plot above shows the fractional parts of for , showing characteristic gaps Trott , p. Already have an account?
