Re: float-to-string

Use the sprintf function:

http://www.ncl.ucar.edu/Document/Functions/Built-in/sprintf.shtml

sprintf gives you better control over number of decimal places and other
number formatting issues. If the "minimum field width" in the %
operator is zero or null, then I think you will get a variable length
string result, with no leading spaces on each number.

Regarding "length of 6", your purpose and formatting assumptions to do
this are unclear. Your dimsizes (stringtochar ()) method will probably
do what you want. But you might consider using a numeric bracket test
instead; it may be more reliable for your purpose. HTH.
