# Output precision

I've solved some equations using FindRoot and then computed some values. Now when I print the output, I only get a certain precision

{{0.01, 496.983, 61.3147, 80., 0.047},
{0.02, 496.983, 61.3147, 80., 0.047},
{0.03, 496.983, 61.3147, 80., 0.047},
...
{0.18, 496.97, 61.3142, 80., 0.047001},
{0.19, 496.969, 61.3141, 80., 0.0470011},
{0.2, 496.968, 61.3141, 80., 0.0470012}}

But when I copy and past the individual numbers, say the 61.3147 in the first two rows, I get

61.314699633952216
61.31469210981553

What can I do to increase the precision of the visible output so I can eyeball it?

• If you don't want to change the global display, you may also try InputForm.(For example, InputForm@RandomReal[{1, 5}, 10]) May 9, 2013 at 3:30
• As a simple workaround, you can just edit the output cell (e.g. add a single space to it). This'll show the full number. May 9, 2013 at 13:40

You must set the option PrintPrecision to a higher value (The default is 6 digits).

• This can be done with the Option Inspector very easily.

• This can also be done programmatically :

SetOptions[SelectedNotebook[], PrintPrecision -> 16]

• It works too with Style[]:

Style[N[\[Pi]], PrintPrecision -> 10]

--> 3.141592654 (instead of default 6 digits :3.14159)
