Number.toFixed() not rounding per specification

Mon 2019.08.26

I'm so hoarse, can't be heard, so decided to create that patch 'fix' as suggested. Used the standard rounding function which is recognized by most:

var roundedNum = ( Math.round( num * 100 )  /  100 ).toFixed( place );

Interactive fiddle Demo

Tried it out in Chrome browser

num= 1.005 place=2
roundedNum= 1.00


num= 1234.505 place=2
roundedNum= 1234.51

Now we are on the right track, or are we???

Test using Espruino WebIDE

num= 1.005  place=2
roundedNum= 1.00
 
  
num= 1234.505  place=2
roundedNum= 1234.50

And, SURPRISE!!   that failed. Is it the toFixed() or the actual Math.round() this time???
