Suppress Scientific Notation in Numpy When Creating Array From Nested List
This is what you need: np.set_printoptions(suppress=True) Here is the documentation.
Display a decimal in scientific notation
from decimal import Decimal ‘%.2E’ % Decimal(‘40800000000.00000000000000’) # returns ‘4.08E+10′ In your ‘40800000000.00000000000000’ there are many more significant zeros that have the same meaning as any other digit. That’s why you have to tell explicitly where you want to stop. If you want to remove all trailing zeros automatically, you can try: def format_e(n): a=”%E” … Read more
Format / Suppress Scientific Notation from Pandas Aggregation Results
Granted, the answer I linked in the comments is not very helpful. You can specify your own string converter like so. In [25]: pd.set_option(‘display.float_format’, lambda x: ‘%.3f’ % x) In [28]: Series(np.random.randn(3))*1000000000 Out[28]: 0 -757322420.605 1 -1436160588.997 2 -1235116117.064 dtype: float64 I’m not sure if that’s the preferred way to do this, but it works. … Read more
Force R not to use exponential notation (e.g. e+10)?
This is a bit of a grey area. You need to recall that R will always invoke a print method, and these print methods listen to some options. Including ‘scipen’ — a penalty for scientific display. From help(options): ‘scipen’: integer. A penalty to be applied when deciding to print numeric values in fixed or exponential … Read more
How can I disable scientific notation?
You can effectively remove scientific notation in printing with this code: options(scipen=999)
