RedCrab Calculator


Prefix mode

Available in RedCrab PLUS
In the prefix mode, the prefix symbol is written in the result instead of an exponent. To do this, select the Prefix option in the format menu on the toolbar. The format menu button is outlined in red in the picture below.
For example, if the prefix mode is on, the result will be written 12m for a current of 0.012 amp instead of 12 ∙ 10-3. The m stands for Milli; So here for milliamps.
The Prefix auto setting uses the prefix that corresponds to the technical exponent. As described above, m takes 10-3. You can also specify a specific prefix or area. How to preset prefixes read here.
