Floating Point Numeric Controls and Indicator

[ASpikes]

Hello! I have an assignment that wants me to have 4 floating point numeric controls and 1 floating point indicator. I'm not really 100% sure what this means, or where to find them. Can someone direct me to where they would be? I am using Labview 2018.

I would recommend looking at the online LabVIEW tutorials
LabVIEW Introduction Course - Three Hours
LabVIEW Introduction Course - Six Hours

Ah, thanks, I had a feeling this is what that was but she hadn't been referring to them as that before so I thought they may be something new 😛

You say "... not really 100% sure what this means ...", but you don't say what confuses you. What is "this"?.

A control is a data source where new values can be input by the operator while the program is running. An indicator is a data sink and  just displays existing wire data, e.g. the internal result of a calculation obtained from the values of controls. The value of an indicator cannot be directly changed by the user at run time. Any given wire can only have exactly one source, but can be branched to an unlimited number of indicators.

Obviously, you now know where to find numeric controls and indicators, but are you also 100% certain what "floating point" means and how they e.g. differ from "integer" numerics? These are core programming principles, so make sure you study this, look it up, or even ask your teacher.

For most numeric controls and indicators, you can freely chose the numeric representation appropriate for the task. In your case you should probably go with the default, i.e. DBL.

And,  while you are learning.. the DBL measn double precision floating point number.  IEEE 754 standardizes how computers represent numbers that are not whole numbers  the kind with a radix separator  like 2.5, e, PI,etc....  in LabVIEW orange wires denote floating point values
