Hello,

I am trying to round the values with two decimals but when the last digit is rounded to zero, zero does not show up. I need every number to be rounded with two decimals even if the last digit is zero. I could not find the code for that. Please see the code that I use below: 

fixnum(round(variable, 2))

I used fixnum because I need to have a comma other than a dot while presenting it.  As an example: It turns "27,17" if the number is "27,167826" but turns "27,1" if the number is "27,102153" while I need it to be "27,10" if possible. 

I will appreciate if you could help.

 

Hm,
yes, that's mathematics.

So, you may do some string manipulations like
{if(strpos(fixnum(round(Q1,2)),'.')==0,join(fixnum(round(Q1,2)),'.00'),if(strpos(fixnum(round(Q1,2)),'.')==strlen(fixnum(round(Q1,2)))-2,join(fixnum(round(Q1,2)),'0'),fixnum(round(Q1,2))))}

The long version.
If you calculate the fixnum part in a separate equation (eqfix), it is
{if(strpos(eqfix,'.')==0,join(eqfix,'.00'),if(strpos(eqfix,'.')==strlen(eqfix)-2,join(eqfix,'0'),eqfix)))}

You have to adapt comma vs. dot.


 

Thank you so much for the quick reply.

Hello,

How I should manipulate the code to have it rounded, such that there is only one true decimal, and the second decimal is zero. Hence, if the number drawn is "30,232", the page should display “30,20”. If "30,252" is drawn, it should display “30,30”?

Round to one decimal.

Round to one decimal.

Hahahaham, I don't think that will solve his or her problem.

They want x.xx in any case, even if it is 1.70 (not 1.7).

If they round to one decimal, the same can happen, only 1.0 would turn to 1.

Oh, no
you see the initial requirement was to have two decimals always.
LSWipo used the rounding fixnum(round(Q1,2))
And I proposed the solution
{if(strpos(fixnum(round(Q1,2)),'.')==0,join(fixnum(round(Q1,2)),'.00'),if(strpos(fixnum(round(Q1,2)),'.')==strlen(fixnum(round(Q1,2)))-2,join(fixnum(round(Q1,2)),'0'),fixnum(round(Q1,2))))}

Now there was the next requirement

that there is only one true decimal, and the second decimal is zero

This is covered by doing the rounding to only one decimal. The displayed number of decimals is done by the string manipulation.
{if(strpos(fixnum(round(Q1,1)),'.')==0,join(fixnum(round(Q1,1)),'.00'),if(strpos(fixnum(round(Q1,1)),'.')==strlen(fixnum(round(Q1,1)))-2,join(fixnum(round(Q1,1)),'0'),fixnum(round(Q1,1))))}

But now I see that my screenshots were missing.
