Using fwrite and controlling decimal places

[Meredith Croke]

Hi Everyone,
 
I am new to GrADS and am trying to write a file that has 10 columns of
temperature readings for over 600 times.  The problem I am running into
is controlling how far the number extends beyond the decimal point.  I
would like there to only be two digits.  I tried using 'set dignum 2',
but this didn't work, and from what I can tell it is mainly used for
plotting.
 
My write line is as follows: f=write (test.dat, ds' 'hs' 'df' 'hf'
0'fff' 'TF' 'TF1' 'TF2' 'TF3' 'TF4' 'TF5' 'TF6' 'TF7' 'TF8' 'TF9,append)
 
Where all the TF's are the temperatures that I would like to only have 2
numbers after the decimal point.
 
Is there some format statement I can put in that would fix this problem?
 
Thanks for your help!
 
Sincerely,
 
Meredith
