The [[Toolchain:MCPCleanup]] utility has many functions, one among them is to convert known constants into code representation for easier visualisation.
== Constants ==
The known substitutions are:
* <code>1.7976[0-9]*[Ee]+308[Dd]</code> -> <code>Double.MAX_VALUE</code>
* <code>3.1415[0-9]*[Dd]</code> -> <code>Math.PI</code>
* <code>3.1415[0-9]*[Ff]</code> -> <code>(float)Math.PI</code>
* <code>6.2831[0-9]*[Dd]</code> -> <code>(Math.PI * 2D)</code>
* <code>6.2831[0-9]*[Ff]</code> -> <code>((float)Math.PI * 2F)</code>
* <code>4.7123[0-9]*[Dd]</code> -> <code>(Math.PI * 3D / 2D)</code>
* <code>4.7123[0-9]*[Ff]</code> -> <code>((float)Math.PI * 3F / 2F)</code>
* <code>0.7853[0-9]*[Dd]</code> -> <code>(Math.PI / 4D)</code>
