[Getdp] function of a discrete value defined piecewise

[Ruth V. Sabariego]

Hi Max,
Try to use a register for storing the quantity before doing the comparison. That way the types will be correct.

E.g. register 22:
Function {
 ...
 mu[] = $1#22 > T_c ? mu_1 : mu_2;
}

This is indeed an old bug!
Regards,
Ruth
