Routine : GetFloatField
Purpose : Reads the next float field from the file.
If no field exists, or EOF is encountered, then Success will be returned FALSE, else
returns a pointer to the float and Success will be returned TRUE.
Leaves the file pointer at the beginning of the next field (i.e.,
skips all delimiters).
