# What Is PDF Full Form

## PDF Full Form in Information Technology : Portable Document Format

PDF Full Form is Portable Document Format which is a file format and file extension. This is developed by Adobe that permits users to capture the native appearance of a document.  It’s useful because the way of printing and viewing the docuent on any device is same like other type of documents. PDF files are frequently utilized in legal documents, like tax papers, bank statements, and other forms that require the user to fill in data.

## PDF Full Form in Science : Pair Distribution Function

The distribution of distances between pairs of particles contained within a given volume is known as  pair distribution function. Mathematically, if a and b are two particles in a fluid, the pair distribution function of b with respect to a, denoted by is the probability of finding the particle b at distance from a, with a taken as the origin of coordinates.

## PDF Long Form in Math : Probability Density Function

In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would equal that sample. In other words, while the absolute likelihood for a continuous random variable to take on any particular value is 0 (since there are an infinite set of possible values to begin with), the value of the PDF at two different samples can be used to infer, in any particular draw of the random variable, how much more likely it is that the random variable would equal one sample compared to the other sample.
