Option to specify the amount of decimal digits

[GuiRitter]

Hi everyone.

I suggest the addition of an option to limit the maximum amount of decimal digits that are output, additionally with the option to choose between truncation and rounding.

If I understood correctly, as it stands, I have to parse the output of the GcodeDriver to extract the values, treat them and reformat the output.

Thanks in advance.

EDIT: finally managed to do it with regex. Using the example from the readme.md and considering no more than 3 decimal digits:

var Gcanvas = require('gcanvas');

var driver = new Gcanvas.GcodeDriver({
  write: function(cmd) {
    // matches a period plus 4 or mode digits; works globally
    console.log(cmd.replace(/[.]\d{4,}/g, match => match.substring(0, 4)));
  }
});

var ctx = new Gcanvas(driver);

Note that this will probably fail if gcanvas outputs commands like G5.1 and you want to remove all decimal digits... Also, I completely disregarded commands that are not movement commands.

I don't have a CNC machine anymore. I added you as a collaborator if you want to work on the project.

Thanks, I'm honored but I don't have conditions right now to help, I'm sorry.
