mfrac

mfrac is a LaTeX command used to typeset fractions. It is part of the amsmath package, which is commonly used for mathematical typesetting in LaTeX documents. The basic syntax for mfrac is \frac{numerator}{denominator}. For example, \frac{1}{2} will render as 1/2.

The mfrac command is versatile and can be used for any kind of fraction, whether it involves simple numbers, variables, or more complex mathematical expressions. When used within a math environment, such as $...$ or \[...\], LaTeX automatically handles the proper spacing and sizing of the numerator and denominator.

In display math mode (e.g., using \[...\] or the displaymath environment), the fraction is typically rendered in a larger, more prominent size with the numerator stacked directly above the denominator. In inline math mode (e.g., using $...$), the fraction is usually displayed in a smaller size, often with the numerator and denominator placed diagonally to save vertical space.

The amsmath package also provides related commands for fraction-like structures. For instance, \genfrac is a more general command that allows for customization of the fraction delimiters and stacking style. However, mfrac remains the most straightforward and widely used command for standard fractions. Proper use of mfrac contributes to clear and professional mathematical documents.
