Extract number after dot google sheets

Question

I have this Google sheets example. with a column of digits

Input
37.39850912456523, 176.84092312542114
37.39850912456523, 17.84092312542115
37.39850912456523, 1.84092312542116
37.39850912456523, 176.84092312542117
3.39850912456523, 176.84092312542118
07.39850912456523, 176.84092312542119
3.39850912456523, 176.84092312542120
3.39850912456523, 6.84092312542121

I attempted this formula to get the progress table.

=ArrayFormula(REGEXEXTRACT(A2:A9, "\d{1,3}\.(\d*), \d{1,3}\.(.{5})"))

And when trying to get the 5 digits after the dot on the first capture group with .{5} or \d{5} i get this error.

=ArrayFormula(REGEXEXTRACT(A2:A9, "\d{1,3}\.(.{5}), \d{1,3}\.(.{5})"))

Error
Function REGEXEXTRACT parameter 2 value "\d{1,3}.(.{5}), \d{1,3}.(.{5})" does not match text of Function REGEXEXTRACT parameter 1 value "37.39850912456523, 176.84092312542114".

Progress
39850912456523	84092
39850912456523	84092
39850912456523	84092
39850912456523	84092
39850912456523	84092
39850912456523	84092
39850912456523	84092
39850912456523	84092

What am I missing to get this result with REGEXEXTRACT?

Desired output
398509	840923

Answer 1

those look like coordinates so better to TRUNC them:

=INDEX(IFERROR(1/(1/TRUNC(SPLIT(A1:A, ", "), 6))))

if you want it regexed try:

=INDEX(IFERROR(SPLIT(REGEXREPLACE(A1:A, "(\d+.\d{6}).*(, \d+.\d{6}).*", "$1$2"), ",")))

---

=INDEX(IFNA(REGEXEXTRACT(A:A, "(\d+.\d{6}).+ (\d+.\d{6})")))

and multiply by 1 if you need values
