.. attention::
A "parse" routine to convert a string into a floating point number is suspiciously absent.
This is because unfortunately there is no such routine available on each of the compiler targets.
Only the C64 target has the ``floats.FREADSTR()`` kernal routine that parses a string into a float into FAC1,
but the X16 has no equivalent in the kernal rom at this time.
The same is true for parsing an *integer* number however you can use the parse routines in the ``conv`` module as
a stepping stone to eventually load the number into FAC1 using one of the available kernal routines.
