The **Standard Part Function**, often denoted as \\( \\text\{st\}(x) \\), is a mathematical function used primarily in the field of non-standard analysis. Non-standard analysis is a branch of mathematics that extends the standard framework of calculus and allows for the rigorous treatment of infinitesimals—quantities that are smaller than any positive real number but larger than zero.
