### rounding number after calculating celsius?

Posted:

**Fri Sep 06, 2013 6:56 am**I would like to have my custom HMI show one of my temps as F and also as C...

I have the following :

and it displays many digits after the decimal point...

I have tried:
and
and they just don't work... not really sure what I am dealing with...

I have the following :

Code: Select all

```
var Temp3 = ultemps[ULTMP_TMP + 3]/10;
var Temp3c = (((Temp3 - 32)*5)/9);
.
.
ctx.fillText(Temp3 + "F " + Temp3c + "C", 200, 132);
```

I have tried:

Code: Select all

```
var Temp3 = ultemps[ULTMP_TMP + 3]/10;
var Temp3c = round(((Temp3 - 32)*5)/9);
```

Code: Select all

```
var Temp3 = ultemps[ULTMP_TMP + 3]/10;
var Temp3c = math.round(((Temp3 - 32)*5)/9);
```
