Hello,

a colleague just noticed the following (erroneous) behavior in Maple 10 :

> a := Psi(2, 2+2*I);
a := Psi(2, 2 + 2 I)
> printf("%+.6e\n", Re(a));
Error, (in fprintf) number expected for floating point format
> evalb(Im(a) <> 0);
false

The behavior is correct in Maple 9.5 :

> a := Psi(2, 2+2*I);
a := Psi(2, 2 + 2 I)
> printf("%+.6e\n", Re(a));
+3.902435e-02
> evalb(Im(a) <> 0);
true

-- Regards,

Franky.
