Description:
 def _sexagesimalize_to_float(value):
 """Decompose `value` into units, minutes, and seconds. Note that this routine is not appropriate for displaying a value, because rounding to the smallest digit of display is necessary before showing a value to the user. Use `_sexagesimalize_to_int()` for data being displayed to the user. This routine simply decomposes the floating point `value` into a sign (+1.0 or -1.0), units, minutes, and seconds, returning the result in a four-element tuple. (1.0, 12.0, 3.0, 4.5) (-1.0, 12.0, 3.0, 4.5) """
