source code error for tutorial: Pixl.js Wireless Temperature Display

It looks like there is a minor typo for the tutorial http://www.espruino.com/Pixl.js+Wireless+Temperature+Display

in this line:

g.drawString(`${dev.name}: ${d.getUint8(0)}'C (${d.getUint8(0)}% bat)`,0,idx*6);

the battery level is displayed twice...

looks like that should reference a different element & read:

      g.drawString(`${dev.name}: ${d.getUint8(1)}'C (${d.getUint8(0)}% bat)`,0,idx*6);

Also, in this same tutorial, I notice that making a slight adaptation to the puck code:

		console.log("temperature: ", E.getTemperature());

gives a decimal temperature, e.g. "24.5",

yet the Pixl.js only displays the integer part with this

${d.getUint8(1)}'C

any hints for how to extract the entire decimal part?
