   soroban.showNumber(9) - takes about 1 ms
2. Multiple digits number (e.g. temperature)
   basic.showNumber(25) - takes about 2657 ms
   soroban.showNumber(25) - takes about 1 ms
3. Multiple digits number (e.g. Pi)
   basic.showNumber(3.141) - takes about 4458 ms
   soroban.showNumber(3.141) - takes about 1 ms
