[julia-users] Type mismatch: MethodError, !Matched::Int64, etc...

this problem could be solved by replacing all my "Float64" and "Int64" by "Number". Is that the good practice? Wouldn't it make my code slower as the exact type is not defined? thanks for any help! have a nice last day of Gregorian year! ;) Charles -- Um axé! :)
