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

^^^ this format is no longer supported starting with
3.0, just skip the
square brackets, now it is working like in C.

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

That should work, indeed.

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.
