[ncl-talk] unexpected results from very simple code

[danghy at gmail.com]

Dear all,

I met a problem when reading "station ID" - I've simplified the code as follows:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
begin
 
degrees = (/210200051, 121, 36, 43,38,58,26/)

print(sprintf("%9.0f",degrees(0))) 
print(tostring(degrees(0)))

a=210200051.
print(tostring(a))
print(sprintf("%9.0f",a))

end

The NCL output on screen is:

(0)     210200051
(0)     210200048.000000
(0)     210200048

Only the second method "tostring" gives the correct station ID.  Could you please give me a clue why is this happening? 

Appreciate!
