10.350000regex currently used by parser for numbers :
[-]?[0-9]*[.]?[0-9]+([eE][-+]?[0-9]+)?does having a [0-9]+ ( ie one or more ) after a [.]? ( ie zero or one )
make the [.]? zero or one mandatory ?
how about :
[-]?[0-9]+[.]?[0-9]*([eE][-+]?[0-9]+)?this removes the possibility to start at the decimal separator ( eg : .56 ) shrug
