(get-value (0.0)) gives ((0.0 0)) , missing decimal point

[jwaldmann]

this is confusing our parser (see https://github.com/yav/simple-smt/issues/20)

$ echo "(set-logic QF_LRA)(check-sat)(get-value (0.0))" | yices-smt2 --smt2-model-format
sat
((0.0 0))

other solvers output the decimal point:

$ echo "(set-logic QF_LRA)(check-sat)(get-value (0.0))" | cvc5 --produce-models
sat
((0.0 0.0))

I am using yices from recent Fedora
