Vincent SmitParticipantBrendan,
Maybe this is beyond the possibilities of Tap Forms. However is it possible to create a calculation field with an “if then else” condition? In case, yes, how does it look like. Also, are trigonometric calculations possible? I’m rather new to Tap Forms. Currently I’m making a database without problems although would like to add some technical calculations.

BrendanKeymasterHello Vincent,
Yes, Tap Forms supports the following functions in the Calculation field formula editor:
SQR
SIN
COS
ATAN
SINH
COSH
COTAN
TAN
EXP
LN
LOG
SQRT
POW
LOGN
ABS
SIGN
TRUNC
CEIL
FLOOR
RND
INTPOW
MIN
MAX
MOD
IF
SUMThe IF statement takes 3 parameters as follows:
IF([Price] > 100, 1.05, 0.0)
So if the value of the Price field is greater than 100, return the value 1.0.5, otherwise return the value 0.
It’s something I need to add to the manual to explain a bit more.
Thanks,
Brendan

Ryan FlyntParticipantJust trying to clarify. I am attempting to do an if then with text for a greeting in a form letter.
Basically, I have two fields, First Name 1 and First Name 2. My goal is here is to have a calculated field called “Greeting” that, if the First Name 2 field is empty, it will only use the First Name 1. Here’s what I have:
IF ([First Name 2] is null, [First Name 1] + “,”, [First Name 1] + ” and ” + [First Name 2] + “,”)
When both are full, works like a charm.
When First Name 2 is empty, I get the result:
Nameinthefield and
Am I not doing this right?

Ryan FlyntParticipantI see now that this doesn’t work with text. I was looking at another calculated text field.
My apologies for the irrelevant post…although I will say that I would find this functionality extremely useful in a future release.
Thanks,

BrendanKeymasterHi Ryan,
Ya, unfortunately the IF statement is very dependent on the values being numeric. But I agree it would be useful for text too.
Thanks,
Brendan

Cliff TarranceParticipantOh yes! I vote for that too! Please make it possible to use conditional tests to concatenate text. For example, I have separate fields for first, middle and last names, plus a display field for the full name. I would like to concatenate first + ” ” + (middle + ” ” +) last, but omit the (middle + ” ” +) if the middle field is null.
thanks,

LeoParticipantBrendan,
does the syntax for these functions follow excel/numbers?

BrendanKeymasterHi Leo,
Most of the functions take one parameter, a few two, some more. I’ll have to put together a list with better examples. I’m off to sleep now, so I’ll do it tomorrow.
Thanks,
Brendan

BrendanKeymasterI finally got around to adding a Calculations field sub-topic to the online user manual:
