# Why does calc get confused by .setFormula('=MAX(4.5,3)')?

I've been using setFormula in my python calc macro for a few days, and it's worked fine with all the '=(A4 * B4) -D3' formulas I've needed. But now I need to use some functions, and it's acting flaky. For the line:

```
sheet.getCellByPosition(column, row).setFormula('=MAX(4)')
```

The cell content is `4`

(as expected).

```
sheet.getCellByPosition(column, row).setFormula('=MAX(4,3)')
```

The cell content is `#NAME?`

That is *not* what I expected.

If I double=click on the `#NAME?`

cell, I see the correct formula (`=MAX(4,3)`

). If I then ^A to select the formula, ^X to cut it, and ^V to immediately paste the formula back in, then hit Enter, the cell responds with the correct value of `4`

.

This is the simplest form of the problem I could find. I found it because this much longer formula:

```
setFormula('=-' + quantity_cell + '*100*MAX(((0.25*' + underlying_cell + ')+MAX(' + underlying_cell + '-' + strike_cell + ',0) +' + price_cell + '), (0.15*' + strike_cell + '+' + price_cell + '))')
```

Behaves the same way, except instead of `#NAME?`

, the error in the cell is `Err:508`

. Again, an in-place cut and paste will make the formula work, but I'd like to have calc display it correctly without the intervention.

I suspect this is a bug, but perhaps there's a work-around?

This is LO 5.1.2.2, and the problem occurs under Ubuntu 16.04 and Windows 10.
