Can't do calculation on PerfMon replys

Offer · Post by **Offer** » Mon Dec 13, 2010 10:51 am

Hello.

I'm using a performance monitor to retrive numbers that are between 0 and 1. For convience purposes - I want to multiply the answers by 10, so I'll get numbers between up to ten.

The problem is that when I try to enter the expression %suggestedreply% * 10 - I get error "unknown operand "0.74"".

I understand the reason is that HM treats the answer as string instead of real number. Using the %suggestedreply_integer% will not help me, because it truncates the fraction after the decimal point.

Many thanks at advance for a possible solution.

Use ['%SuggestedReply%' * 10] expression

Thanks, Alex.

Simply a genious. (I assume the ''' is converter from string to numeric value?)

Just a little problem stayed:
When I use that formula, I get only Integer numbers as result. (For example - 0.74 becomes 7 after the formula). How can I get 7.4?

Thanks!

Sorry, don't see such option

HostMonitor rounds results of "Tune up Reply" expression because most of test methods provide integer results only...

Dear Alex.

Thanks for your answer.

I've tried to be a little genious myself, and here what I came with:
[('%SuggestedReply%' * 1000) div 100].[('%SuggestedReply%' * 1000) mod 100]

What do you think about this? It seems to give the wanted results. Isn't it?

Thanks again.

Goog idea!
I was thinking about similar expressions but was worried by rounding.
This expression should work fine when 1-2 digits after dot is enough.
