Hi,

The value that I want to keep in a variable, a, is
1.24500000476837.
After I define as
IDL> a = 1.24500000476837
then, print, a
IDL> print, a
IDL> 1.2450000
so, I tried
IDL> a = 1.24500000476837d ;; to make it as a double precision, but
IDL prints
IDL> help, a
A DOUBLE = 1.2450000
IDL> print, a
1.2450000

How can I keep all those decimal points?
I thought double precision can express up to 14 decimal places of
significant points?
