What if I dont know that the float will
be 8 in length and has 6 decimals ??

How can we put this in a subroutine, that handles
a variable (e.g. PRO FORMAT, var1) and returns
the right way to print ??

For the int I use

PRO FORMAT, var
which=SIZE(var, /TYPE)
if (which eq 2) then begin
le=FLOOR(ALOG10(var)) + 1
RETURN, STRING(var, FORMAT='(I'+STRTRIM(STRING(le))+')'
endif else if (which eq 4) then begin

How do I do this for a float >>>??
1.22222200000 must become 1.22222 without leading or trailing spaces.
And in the best scenario 1.00 doesn;t become 1., but 1.0 ....
