How do I round number from 15 digits after decimal point to 6 in robot framework?

I need to round 41.800000000000004 to 41.8000000

I tried 'convert to number' but it outputs the same, there is no 'convert to float' and 'convert to integer' will delete the decimals

I think it might be possible with 'format string' or some sort of string length manipulation but I'm unsure how to do that

Solution

  • You see, the value 41.8 seems the correct float representation of your number rounded to 6 decimal points.

    To keep trailing zeros, you need to use string format, as they, not meaningful zeros, disappear in float representation.

    As one of the options, you could use string Format Specification Mini-Language.

    As Robot Framework line:

    evaluate '{0:.6f}'.format(41.800000000000004)

    --> '41.800000'
