signif_half_up

In base R <code><a href="/link/signif()?package=janitor&version=2.2.0" data-mini-rdoc="janitor::signif()">signif()</a></code>, halves are rounded to even, e.g.,
<code>signif(11.5, 2)</code> and <code>signif(12.5, 2)</code> are both rounded to 12.
This function rounds 12.5 to 13 (assuming <code>digits = 2</code>). Negative halves
are rounded away from zero, e.g., <code>signif(-2.5, 1)</code> is rounded to -3.
This may skew subsequent statistical analysis of the data, but may be
desirable in certain contexts. This function is implemented from

The main janitor functions can: perfectly format data.frame column
names; provide quick counts of variable combinations (i.e., frequency
tables and crosstabs); and explore duplicate records. Other janitor functions
nicely format the tabulation results. These tabulate-and-report functions
approximate popular features of SPSS and Microsoft Excel. This package
follows the principles of the "tidyverse" and works well with the pipe function
%>%. janitor was built with beginning-to-intermediate R users in mind and is
optimized for user-friendliness.
