isEmpty (field) & GetAsNumber (field)

Hello everyone,

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 ?


Thank You,
