Defining type of dataset and data format

Hi guys

I have quick question. I have numbers 0.354, 0.125, 0.058, 0.023.... What kind of data type is these numbers? Also what kind of data format? Is it called integer data?

Thanks!

None of those entries are integers. The representation you have shown us is decimal values, but it is unlikely that decimal was used to store them (they would print out differently if it was.)

Those numbers appear to be floating point values. Not enough information has been given to say whether they are IEEE 754 Single Precision ('single') or IEEE 754 Double Precision ('double', which is the default.)

You can use class() to query the data type. You can also use whos to look at information about the variable.

Thanks Walter for helpful response! By typing class() I find out it is double type of format. But for data I don't know yet,cause whos is giving error by saying

Argument must contain a string.

So it not surely integer, not real number, neither text value. I don't know what kind of data type left.

[Walter Roberson]

If the variable name is data, then instead of

whos(data)

use either

whos data

or

whos('data')

Okay, thanks whos data worked. It did not say anything about data type. I guess it is real number. Thanks a lot for your time!
