error in subst function

[hata]

Hi all

In CAS mode, with (non-CAS) variable T initialized to 100:

subst('S + 10', 'S=T') yields T+ 10 (desired result)
subst('S + 0.1', 'S=T') yields 100.1 (which is not correct)

Using CAS variables s and t leads to same strange behaviour.

ANyone, any explanation for this ? Seems like an error to me ...

Thanks for your help.
