I see two obvious choices, both of which are reasonably simple, neither of
which is exact:
1) Write the value as a string representing a floating point value with as
many significant digits as possible. Use an Ada.Text_Io to convert the
value to a string, trim the string and add it to the XML text.
2) Write the value as an integer value. Since you are dealing with cosines,
the range of values are between -1.0 and 1.0. These could be mapped between
the integer values of 0 to 2^32-1, (or -2^31 to 2^31-1, take your pick).
This would give you a precision of 1/(2^32), which may be sufficient for
your application. You may be able to handle this directly by defining a
fixed point type in Ada.
I hope this helps,
Steve
