AsNumber(value)
This function converts the value to number. This is useful when you wish to validate the contents of a field or retrieve the number value of a field.
- Text should have only digits and one decimal point.
- Boolean is converted into -1 (TRUE) or 0 (FALSE).
- Number remains itself.
- Everything else returns error.
| Example | Result |
|---|---|
| asnumber( 0 - 13 ) | -13 |
| asnumber( 2 + 2 = 4 ) | -1 |
| asnumber( 1 > 2 ) | 0 |
| asnumber( 'text' ) | #Can't convert to number |
| asnumber( ) | #Can't convert to number |
