Negative exponents are calculated incorrectly without parenthesis

[Delta-official]

As of 1.9.2, cpc incorrectly calculates the sign of negative exponents without parenthesis

Expression	Result	Expected
-3^2	9	-9
(-3)^2	9	9

Hmm it's a bit tricky. - may or may not take precedence over ^ depending on it's position:

-3^2 == -(3^4)
3^-2 == 3^(-2)

Nevermind, not that tricky. Released the fix in v1.9.3
