Round off a number

I have a scenario where @Num_calculated = 1.306 and @Num_actual = 1.31, and I have to do a Compare between these two values but it's failing. Is there any way to round off @Num_calculated to 2 decimal digits in Subject7 ?

Hi Raunak,

Please try the following:

Math.round(1.306 * 100) / 100

Here is a sample test case to show that both numbers are rounded to 2 decimal (i.e. value of 1.31) and pass the equality assertion just fine:

SET VARIABLE Num_calculated VALUE EXPRESSION "Math.round(1.306 * 100) / 100" HALT ON ERROR
SET VARIABLE Num_actual VALUE EXPRESSION "Math.round(1.31 * 100) /100" HALT ON ERROR
COMPARE @Num_calculated EQUAL @Num_calculated AS TEXT HALT ON ERROR

Please let us know if this solves your issue.

Hi Raunak,

Could you please provide a screenshot of the command options for Compare that you used and provide a screenshot of the failure?

This is the error message:

And this is the command options:

In Set_Var command, for the source type as EXPRESSION, can we use variables using @ to refer to them ? for example: in 'Math.round(1.306 * 100) / 100', can we use @Num in place of 1.306 like 'Math.round(@Num* 100) / 100' ?

Hi Raunak,

Yes, of course you can use variables in Set_Var with expression.

I have been trying to use variables in set_var expression type but it throws an error as follows:

Hi Raunak,

Can you run the same steps in a new test case, like below. I just ran it and it passed.

Raunak, what version of Java are you using?

Raunak Nandy (US - ADVS) February 17, 2021 03:48

I am using OpenJDK version 15.0.1

Payam Fard February 17, 2021 03:50

Please use Java 8 or 11 instead. This issue has to do with Java 15. Please update this thread once you downgrade your Java version.

I downgraded to Java 11.0.2 and now it's working fine, thanks for your support !

You are most welcome, we're glad it's working.
