Introduction
The following table provides a summary of the ad-hoc rules.
Ad-hoc operations on variables and table cells containing or assigned with numerals:
| Operator | Description | Operator | Description | Operator | Description |
|---|---|---|---|---|---|
| ++ | Increment by 1 | -- | Decrement by 1 | ** | Syntax error (factor missing) |
| ++ ++ | Increment by 2 | -- -- | Decrement by 2 | ** ** | " |
| ++ (3) | Add 3 | -- (3) | Subtract 3 | **(3) | Multiply by 3 |
| ++ (-3) | Subtract 3 | -- (-) | Add 3 | **(1/3) | Divide by 3 |
Ad-hoc operations on variables and table cells containing or assigned with blank strings '' assumed zero:
| Operator | Description | Operator | Description | Operator | Description |
|---|---|---|---|---|---|
| ++ | Sets to 1 | -- | Sets to -1 | ** | Syntax error (factor missing) |
| ++ ++ | Sets to 2 | -- -- | Sets to -2 | ** ** | " |
| ++ (3) | Sets to 3 | -- (3) | Sets to -3 | **(3) | 0 Multiplied by 3 = 0 |
| ++ (-3) | Sets to -3 | -- (-) | Sets to 3 | **(1/3) | 0 Multiplied by 3 = 0 |
Ad-hoc operations on variables and table cells containing or assigned with non-blank strings have no impact, and cause no exceptions.
Ad-hoc operations on variables and table cells containing or assigned with blank dates date('') have no impact, and cause no exceptions.
Note: Table cells do only apply if configured to retrieve dates as dates.
Ad-hoc operations on variables and table cells containing or assigned with dates (e.g. date("2020-01-01") ) are supported.
Note: Table cells do only apply if configured to retrieve dates as dates.
| Operator | Description | Operator | Description | Operator | Description |
|---|---|---|---|---|---|
| ++ | Tomorrow | -- | Yesterday | ** | Syntax error (factor missing) |
| ++ ++ | Day after tomorrow | -- -- | 2 days before | ** ** | " |
| ++ (0.25) | Same day | -- (0.25) | Same day | Results in blank date | |
| ++ (3) | 3 days later | -- (3) | 3 days before | **(0) | Results in blank date |
| ++ (3.75) | 3 days later (same) | -- (3.75) | 3 days before (same) | **(1) | Unchanged date |
| ++ (-7) | 1 week before | -- (-7) | 1 week later | **(...) | All other values: Exceptions (dates cannot be multiplied) |
Ad-hoc operations on variables and table cells containing or assigned with dates and times (e.g. date("2020-01-01 12:45:00")) are supported.
Note: Table cells do only apply if configured to retrieve dates as dates.
| Operator | Description | Operator | Description | Operator | Description |
|---|---|---|---|---|---|
| ++ | Tomorrow | -- | Yesterday | ** | Syntax error (factor missing) |
| ++ ++ | Day after tomorrow | -- -- | 2 days before | ** ** | " |
| ++ (0.25) | 6 hours later | -- (0.25) | 6 hours earlier | Results in blank date | |
| ++ (3) | 3 days later | -- (3) | 3 days before | **(0) | Results in blank date |
| ++ (3.75) | 3 days + 18 hours later | -- (3.75) | 3 days + 18 hours before | **(1) | Unchanged date and time |
| ++ (-7) | 1 week before | -- (-7) | 1 week later | **(...) | All other values: Exceptions (dates cannot be multiplied) |
Ad-hoc operations on variables and table cells containing or assigned with and times (e.g. time("12:45:00")) are supported.
Note: Table cells do only apply if configured to retrieve dates as dates.
| Operator | Description | Operator | Description | Operator | Description |
|---|---|---|---|---|---|
| ++ | Exception (not same day) | -- | Exception (not same day) | ** | Syntax error (factor missing) |
| ++ ++ | Exception (not same day) | -- -- | Exception (not same day) | ** ** | " |
| ++ (0.25) | 6 hours later (if same day) | -- (0.25) | 6 hours earlier (if same day) | **(0) | Results in blank date |
| ++ (3) | Exception (not same day) | -- (3) | Exception (not same day) | **(1) | Unchaned time |
Ad-hoc operations on variables and table cells containing or assigned with booleans:
Note: Table cells do only apply if configured to retrieve dates as dates.
| Operator | Description | Operator | Description | Operator | Description |
|---|---|---|---|---|---|
| ++ | Sets to true | -- | Sets to false | ** | Syntax error (factor missing) |
| ++ ++ | Sets to true | -- -- | Sets to false | ** ** | " |
| ++ (3) | Sets to true | -- (3) | Sets to false | **(0) | Sets to false |
| ++ (-1) | Sets to false | -- (-1) | Sets to true | **(1) | Non-zero: Value unchanged |
| ++ (-3) | Sets to false | -- (-3) | Sets to true | **(-1) | " |
Ad-hoc operations on variables containing parameter sets:
All elements will be affected by this operation, including elements in nested parameter sets. This is a clear difference from all other arithmetic operations
where you need to distinguish between regular operators (affects one individual value) and deep operators (affects elements in a parameter set at a specified depth).
Note: No impact on empty cells.
Note: Ad-hoc operations on void values will cause exceptions.
