I realise the print() used by the LiquidCrystal library is the same one used by Serial, and that the Serial spec shows the functionality for print() when passed a float type, but it seems odd to omit it from the LiquidCrystal page. The way it's written, it almost reads like lcd.print() cannot handle float types:
data: the data to print (char, byte, int, long, or string)
Sorry, I'm new here. How are the arduino.cc reference pages maintained? Are they in a git repository somewhere that I can patch?
