[bug] Assigning "0:00" to cell gives an error

[bug] Assigning "0:00" to cell gives an error

[Sebastien Vauban]

Hello,

As shown by this example, we can't assign the value "0:00" to a cell:

| Task    |  HH:MM |
|---------+--------|
| This    |   1:23 |
| Nothing | #ERROR |
| That    |   1:23 |
#+TBLFM: @2$2=1:23::@3$2=0:00::@4$2=4:56

Best regards,
  Seb

Hi Sebastien,

you can use @3$2=string("0:00")

We can assign the value "0:00" to a cell via the string function:

| Task    | HH:MM |
|---------+-------|
| This    |  1:23 |
| Nothing |  0:00 |
| That    |  4:56 |
#+TBLFM: @2$2=1:23::@3$2=string("0:00")::@4$2=string("4:56")

but, *when giving the value via the table formula*

- we can't convert any time (0:00 or H:MM) to a fractional time:

  | Task    | HH:MM |
  |---------+-------|
  | This    | 0.00  |
  | Nothing | na    |
  | That    | na    |
  #+TBLFM: @2$2=1:23;t::@3$2=string("0:00");t::@4$2=string("4:56");t

- we can't confirm that its format must be H:MM

  | Task    | HH:MM |
  |---------+-------|
  | This    | 0:00  |
  | Nothing | na    |
  | That    | na    |
  #+TBLFM: @2$2=1:23;T::@3$2=string("0:00");T::@4$2=string("4:56");T

Those problems do arise in both ways of assigning a time to a cell:

- via the "common" way:  @2$2=1:23

  Results: 0.00

- via the "string" function:  @4$2=string("4:56")

  Results: org-table-time-seconds-to-string:
  Wrong type argument: stringp, (0 "Number expected")

  (I've explicitly written "na" strings which never got replaced, because of
  this error)

Best regards,
  Seb

The :t and :T flags are not assigning a value to a cell.

... same here.

The @4$2=string("4:56") works fine here, without any flag.

I did not express myself clearly, then. Sorry for that.

The assignment is done through the `=' sign. This is the "what" part of the
equation, that is the value which is assigned to the cell.

The flags are the "how" part of the assignment. At least, they should tell
about the formatting of the value (like for numeric assignments), but they
don't (for time assignments).

Let's compare with numerics:

  @2$2=3.141592;%.2f

The value just follows the equal sign: pi is *what* to output in the cell. The
flag (here, `%.2f') says *how* to output it, in this case limited to 2
decimals.

Let's come back to time values:

  @2$2=1:23;t

means, for me, that:

- the value 1:23 should be assigned to the cell
- that value should be formatted as a fraction.

Hence, I'd expect to see `1.38' (and not `0:00').

This works correctly now, thanks.

I confirm that the above case works correctly now, as shown here:

| Task    | HH:MM |
|---------+-------|
| Foo     |  1:23 |
| Bar     |  1.38 |
| Nothing |  0:00 |
#+TBLFM: @2$2=1:23::@3$2=@2$2;t::@4$2=string("0:00")

Thanks.

Best regards,
  Seb
