Arithmetic Functions
-compat Argument
When the -compat argument is active, the following arithmetic function/operator rules apply:
• log(x) = sign(x) × log(abs(x)).
• log10(x) = sign(x) × log10(abs(x)).
• db(x) = sign(x) × 20.0×log10×abs(x)).
• sqrt(x) is −sqrt(abs(x)) if x is negative.
• x**y is computed as x ψ if x is positive, x ΙΝΤ(ψ) if x is negative, and 0 if x is 0.
• The power operator (^) has highest precedence (same as standard Eldo).

Note
In Eldo standard mode: sqrt(x) returns an error if x is negative; x**y is computed as
exp(y×log(x)) if x is strictly positive, 0 if x is 0, and returns an error if x is negative.
