Hello,
Is there anything special that needs to be done for float comparison?
For example:
if([5.5 >= 4.3]) ....
or if(5.5 > 4.3) ....
The conditional does not seem to be coming back as true like it should?
This is simply an example... the precision in the actual case is different (longer decimal places).
Thank you for all and any help in advance!

I have no idea if floating point comparison is supported, but you could multiple the values (e.g. * 10000) before comparison

The pseudo-variables can hold integer or strings. Do you do comparison with static values or you load the values in some variables and then compare?

Daniel,
Sorry for taking so long to respond - I am still facing an issue with this (even in 3.1.4).
I am loading the values from database.
It looks as if the arithmetic operators are not functioning properly when the data is imported into kamailio from DB - I'm going to do some more research and give you some specifics.
Sincerely, Brandon Armstead

Hello,
as mentioned before, script variables work only with integer or string values. In this case I suggest you load the values as string and then use Lua to compute what you want as float. Alternative, load as string (n the format integer.decimals) and split the value using transformation in the part before the dot and the part after dot. Then you can do operations with them.
Cheers, Daniel

If you just use fixed-point for fractional values, you can remove the dot and convert to int.
$(var(float){s.replace,.}{s.int})

$(var(float){s.replace,.}{s.int})
By fixed point do you mean when the fractional part has fixed length? That should work, indeed.

Yes.
There was a typo above, syntax should be:
$(var(float){s.replace,.,}{s.int})

OK. I am not familiar with the deep details of database value types - to expect that it is a way that I can get always the trailing 0's for such value? For example, if I want a db column type with 5 decimals in the fractional part, for real value 1.5 I will get 1.50000 Thanks, Daniel

If the column is a NUMBER(n,prec)/DECIMAL(n,prec) type, at least mysql returns it with full precision. In Kamailio they're converted to string, after which the above transformation works.
Maybe even direct string comparison can be used on two fixed point values (as string) with equal precision.
