parseFloat() returns the first valid floating point number from the current position. Initial characters that are not digits (or the minus sign) are skipped. parseFloat() is terminated by the first character that is not a floating point number. The function terminates if it times out (see ../streamsettimeout[Stream.setTimeout()]).

This function is part of the Stream class, and can be called by any class that inherits from it (Wire, Serial, etc). See the Stream class main page for more informatio
