I am trying to write a float value to a file on a SD card. I don't understand why serial.println(float) on works, but file.println(float) does not. If someone can explain this I'd be most grateful. I've tried looking at dtostrf, but honestly I cannot find it in the reference. Thanks.

It compiles but does not write any output.
