Hi all,
I have given below what I have done.
print,julday(10,22,2014,14,00,32),format='(g)'
2456953.083703704
mytimes=timegen(1,units='seconds',step_size=14,start=2456953 .083703704)
The idea is to get julian at this date/time
10,22,2014,14,00,32 and
14 second after this, that is at 10,22,2014,14,00,46
I expect the result to be 2456953.083865741.
But If I do
print, mytimes
2456953.0
Please anybody let me know how to resolve this.
thanks

If you have IDL 8.5 or later, the new "implied print" syntax helps you get around the default formatting of the standard PRINT behavior.
First option, simply type the variable name at the prompt.
IDL> mytimes
2456953.0837037046 2456953.0838657417
This is the same as using PRINT with the /IMPLIED keyword.
IDL> print, mytimes, /implied
2456953.0837037046 2456953.0838657417
The keyword can be unambiguously abbreviated to "/i":
IDL> print, mytimes, /i
2456953.0837037046 2456953.0838657417
There's less typing involved than with an explicit FORMAT string. (But also see the new C-style formatting in IDL 8.6.)

But if I need to get the values in the variable itself without printing, then what should I do,
Because I am going to use the variable in a loop, I want the variable mytimes to have value with 2456953.083703704 format.

The result from TIMEGEN does indeed have the precise values you want, it's just that if you 'print, mytimes' it is only *displaying* to eight digits of precision. Does that clear it up for you?
