Specifying variable's precision programatically

[okinelin]

Hello there,

I am using direct file access to log calculated variables. I want to control the number of decimal points for the log variables.

I have tried format("%.2f", CalculatedVariable) but that doesn't seem to work.

Can someone please help out?

Thanks

%.2f should work provided calculatedVariable is actually a number. What do you get? Its possible that your variable is actually a string.

Below is the variable;

Scaled_Pressure_1 = Pressure_1[0]*Slope_Pressure_1 + Intersect_Press_1

In order to write to a file I used the following code

DoubleToStr(format("%.0f", Scaled_Pressure_1))

and that did not work. Is there anything wrong in the code?

[AzeoTech]

No, provided all those variables actually have values and are numeric. There is certainly nothing wrong with this line:

DoubleToStr(format("%.0f", Scaled_Pressure_1))

Though technically you don't need the doubleToStr() since the format() function makes a string.

You might add a:

? Scaled_Pressure_1

after the calc to see what the result of the calc is, or use the debugger.

Thanks Guru.

It's working. I didn't realize the format() returns a string. I removed the DoublToStr() and everything is fine.

I appreciate your support
