regex match a line with more than 2 non-digits including ^

Question

I want to match lines with negative numbers or/and decimal numbers with a ^.

-1.2^-2.4  
-12^2.4  
-1^2

but not

1^2
1+2

I got [\^\D*]{2,} but it is not working

Thanks in advance

Would this work?

/^((-\d+|\.\d+)\^|.+\^(-\d+|\.\d+))/

matches a negative or decimal number followed by ^ or a ^ followed by a negative or decimal number.

It seems to me you are looking for something like the following.

^(?=.*\D{2,})[-.^\d]+$

This seems to work:

^-?\d+(\.\d+)?\^-?\d+(\.\d+)?$
