Unfortunately, any attempts to use regular expressions that attempt to
retrieve the number before the digit result in an error
$h_X-Spam-Potential:{{^(\\d+).*\$}{\$1}} is above 16
Error in system filter: unrecognized condition word ""
the workaround is to take the whole number and remove the dot
for example, if I want the condition to be met when the number is greater
than 16, I must enter the number 160 in the variable.
${sg{$h_X-Spam-Potential:}{\\.}{}} is above 160
I don't know if it's some kind of error in the system_filter code

Heloo Jeremy
This way the values always have one digit after the decimal point
I just need the number before the decimal point

In exim filter, numeric values in the "is above" rule are only accepted

I have to execute the delivery command if the header value is above
some number,
unfortunately many of them are written in the header and are decimal
numbers, as a result I get an error
error in filter file: malformed numerical string "16.34"
here is my expression
if
$h_X-Spam-Potential: is not "" and
${sg{$h_X-Spam-Potential:}{^(\d+)\..*}{$1}} is above 16
then

theoretically, only the number 16 before the dot should be taken into
account but unfortunately this doesn't happen :( thanks for help Slawek
Do the values have a fixed number of digits after the decimal point?
You could just delete the dot using ${sg...}.
Or if you know there's always at least one, and you only needs tenths,
ditto but only taking 1 digit for the second group.
