Code: Select all
SetGadgetText(3, Str(Val(GetGadgetText(2))*Val(GetGadgetText(1))))
Looks pretty close if I haven't forgotten a bracket.

Hi to everyone....
i have 2 other questions to solve.....
i need to divide like below a gadget /1 but this don't work...
Code: Select all
SetGadgetText(3, Str(Val(GetGadgetText(2))/1
and another problem a little more complicated :
Code: Select all
SetGadgetText(3, roundup (Str(Val(1/GetGadgetText(2))/Val(GetGadgetText(1)*Val(GetGadgetText(4)))))-0,5
I'm a little confused....can somebody help me please???
Best regards,
Lestroso

There is a manual included in PB...
ValF(),
StrF(),
ValD(),
StrD(),
Int(),
Round()

You can't divide like that: SetGadgetText(...)
/1
And you have 4 openig brackets and only 2 closing brackets.

And an additional remark:
Writing text to gadgets, reading text from gadgets and math operations are completely independent from each other. So asking questions like these is not only a strange approach, but also makes things look more convoluted than necessary.
Better use some variables, e.g.:
Code: Select all
a = Val(GetGadgetText(1))
b = Val(GetGadgetText(2))
c = (a + b) * 27
SetGadgetText(3, Str(c))

Hm...
you have 5 fingers on one hand (I hope).
So please count the opening brackets and the closing brackets with the help of your fingers.
If you do it like this, you will see that they don't match.
You know the rule: multiplications and divisions have a higher priority than minus and plus?
You know that float values in a programming language uses a dot as decimal point?
You know, that a variable in PB is an integer if it is not defined?
You know what an integer is?
If you know all these, than you know why your code is not working as expected.
Maybe this is what you want:
Code: Select all
TOT1.f = Round(1 / B4 / D6 * C1 - 0.5, #PB_Round_Up)
But without the original formula, this is only a guess.
