Numeric Comparison

[woreid]

How can I do numeric comparisons? The Mathematics function doesn't work and the other operators do string compares.

[CandiceJones]

Mathematics works, of course. If automatically does numeric comparisons when both parameters resolve to numeric values.

[woreid]

No. Mathematics does not work for me.

That simple program gives me an empty string. Now what?

[CandiceJones]

There's a bug in your code

Var2 = Var1 + 5000

is wrong

$Var2$ = $Var1$ + 5000

is correct

[woreid]

OK. That works, but this doesn't. Checking disk space was how this all started for me.

The value is an Int64 value which is creating the problem. We should have an update for this very soon!

[klavelle]

Is this bug fixed yet?

This still fails:

Get Free Space on C:\\ into variable availDiskSpace

Set Variable reqSpace to 2048000000
Evaluate Expression $availDiskSpace$ >= $reqSpace$ into variable diskSpace

diskSpace will be false, where it should return true ($availDiskSpace$ while running this is well over 2 GB).

Is there any other way to check for free disk space?

[CandiceJones]

You should use If for that. Evaluate Expression performs logical operations on strings only.

[sdeschenes]

I am trying to perform the same operation as Klavelle. I have tried using the Evaluate Expression command, the Eval command provided by the Camelot plug-in and I have used the standard If statement. I have varA set to 1978 and varB set to 16327196672. When I check to see if varA is greater than varB, the Evaluate Expression and Eval commands return True and the if statement also returns true.

You mentioned that the value is an Int64 value. Did you ever get a fix for this?

[CandiceJones]

Yes, try with InstallAware 9.01.
