Hi new,

 

the easiest would be to change the formatting options used for your indicator.

 

On the other hand you want to explicitely ROUND DOWN in contrast to default "bankers rounding" when you want to display "0.12" for a given input of "0.125401" - most would expect a display of "0.13" instead.

So the answer is: multiply by 100, round down, divide by 100, display using a format of %.2f…

Best regards,
GerdW

Getting rid of numbers is very difficult. 

 

Here is a little number that just keeps showing up! Totally unnecessarily

Completely ambiguous questions:

 

What is the datatype of the "number"?

 

  • If it is a string just take the substring from the beginning to 2 characters after the decimal points.
  • If this is a numeric indicators, just change the display format to show two decimal digits (right-click...display format. And yes, that would show 0.13 in your case).
  • If this is a floating point datatype (DBL, SGL) and you want to truncate the actual "wire data" for a fixed number of decimal places, you are out of luck because most fractions that look nice in decimal would need an infinite number of mantissa bits in the internal binary representation. Impossible!

This is one way you can do it, there are many others.
