text in if statements - Сообщения
#1 Опубликовано: 01.05.2019 17:40:54
Can text be included in an if statement? For example:
If "Thin-walled pipe anchored throughout" then P=1-v.
I have various conditions that different formulas would be used depending on the conditions, see below.
If "Thin-walled pipe anchored throughout" then P=1-v.

Hi. You have some options for do that. Here are two:

Easy to complete the conditions, thus the project.

I don't understand how to input the data into the statement. If I press the space key, the input ends, and I cannot input anything.

There is no space key to press. Construct the snippet, done.

Sorry, I have never constructed a snippet before. How do I do that?

Construct the math regions as per the image that we call snippet.

I tried to construct it. My question is how to do that. I try and the below is what happens:

g(str,x):=then from menu f(x), then cases, then fill-in

The cases() function is included into the "custom functions" plugin, so you should also be sure to have it installed.

Thank you. I had the "custom functions" plugin installed, but the use of it is not in any of the manuals, at least not that I could find. I had no idea I had to type the word "cases" to get to the input.

Thank you. I understand now.

I had no idea I had to type the word "cases"
only click the function 'cases' from the f(x) menu.
In the right most place holder of the first 'if'
place the cursor type coma, coma [,,]
that gives another line of conditions ... and so on.

Thank you. I was trying to figure out how to do that.

I use the cases function to type everything in, but when I go back to the first line that says "x if str", as soon as I type "x if str =, as soon as I type the = sign, I get "x not defined". I am trying to understand, but not getting it yet. I had it almost working, but then this glitch appeared.

I figured out how I did it before. I cannot type the = in the above, but it works with a :=. But it does not really work, because if I say str:="b" and x:=7, the answer is 21.99 instead of 14, but it does allow me to type it. I am confused.

Please post the worksheet or a screenshot. In the second column of cases you have to use boolean equals, not the assignment operator.
You can find the boolean operators in one of the palettes on the right of your screen, hovering the mouse hover the symbols you should see the keyboard shortcut.

thank you. I can't use the "Thank" button because every time I do, it says "error occurred"

How do I remove a line. I tried backspacing, and it did not work.
