As pointed out in several AVR programming topics, by default your code links against the minimal versions of libprintf and libscanf. Therefore your Arduino ^TM^ software (if compiled by the default IDE) will lack string-float/float-string conversions, as you might suspect it once tried to sprintf some float to a string and only get question marks on your serial output... There are several options to fix this and link against the float-enabled versions of printf and scanf libraries (present in your Arduino environment).
