Is it bug? CAS solve function.

solve([a+56/10=66/10, -a+3*b-12/10=-22/10],[a,b]) => [[1,0]]

list2exp(solve([a+56/10=66/10, -a+3*b-12/10=-22/10],[a,b]),[a,b]) => a=1 and b=0

exp2list(ans(-1)) => [[1,0]]

Joe already answered your question. If the user wants exact values, then exact inputs are needed (i.e. no decimals).
