`Should Be Equal As Numbers` from BuiltIn automatically converts arguments to floats.

Thanks

I have tried should be equal to Numbers keyword but gives error.

The values are like x=16.442,300  
Another one y=16.442,3  
I have used ‘get text’ to fetch values

Error- can’t convert to floating point number : value error : could not convert string to float : 16.442,300

I have used parse also not worked

Can u help please

At a guess, you’ll probably need to strip out the “,” comma first (but I could be wrong)

Hi pavan,

What’s the source of this number? The reason I ask → [Decimal separator - Wikipedia](https://en.wikipedia.org/wiki/Decimal_separator)

Before you mess with the numbers you should know which of the `.` or `,` is the decimal separator and which is thousand separator?

Dave.

Hi pavan,

I actually meant what country did the source data come from? I see you solved it already 👍
