Yes robtillaart is correct, it inherits the print library, so it has the same capabilities as the Serial library.
Incase you didn't know, the print and println overloads for float accept a precision parameter.
Serial.print( 123.4567f ); <-- This will print "123.46"
Serial.print( 123.4567f, 4 ); <-- This will print "123.4567"
