I have two quick curious questions.
1) The use of isEmpty (FIELD)
Some people use the expression like: if (FIELD_A = “”; …..
others use the expression: If (isEmpty (FIELD:A); …..
is there any specific advantage of using one or the other ?
2) GetAsNumber (field)
When I updated older solutions to FMP14 I found in formulas that the expression was changed
It was like: If (FIELD_B ≠ FIELD_C; …..
Now it looks like: If (GetAsNumber (FIELD_B) ≠ GetAsNumber (FIELD_C); …..
Is there any specific reason the “GetAsNumber” was automatically added ?
