\nprec-Tex Command

\nprec is a LaTeX command that defines the minimum number of digits that should be displayed after the decimal point in a number. It is used when formatting floating-point numbers in scientific or mathematical documents.

Usage
\num[<options>]{<number>}

\num is a command provided by the siunitx package that allows you to format numbers according to various styles and settings.

The \nprec command is part of the <options> argument. It specifies the number of digits after the decimal point that should be displayed. For example, \num[noprec]{3.14159265359} would display the number as "3.14159", while \num[noprec]{3.14159265359} would display the number as "3.14159265".

You can also use \nprec as a standalone command to set the number of digits for all subsequent \num commands in the document. For example, \nprec{3} would set the number of digits to 3, and all subsequent \num commands would display numbers with 3 digits after the decimal point.

Examples

Here are some examples of using the \nprec command:

\num[noprec]{3.333333333333333}
% Outputs: 3.333333333333333

\num[noprec]{3.333333333333333}\nprec{2}\num[noprec]{3.333333333333333}
% Outputs: 3.333333333333333  3.33  3.333333333333333

\num[noprec]{3.333333333333333}\nprec{1}\num[noprec]{3.333333333333333}
% Outputs: 3.333333333333333  3.3  3.333333333333333

\num[noprec]{3.14159265359}\nprec{5}\num[noprec]{3.14159265359}
% Outputs: 3.14159265359  3.14159  3.14159265359
Conclusion

\nprec is a useful tool for formatting decimal numbers in LaTeX. It allows you to control the number of digits displayed after the decimal point, and can be used with the \num command provided by the siunitx package.
