To convert 64-bit DECIMAL or NUMERIC values to a higher precision, you must use an explicit conversion function such as the CAST or CONVERT functions. When converting DATE or TIMESTAMP to TIMESTAMPTZ, or converting TIME to TIMETZ, the time zone is set to the current session time zone.
Dec 11, 2020 · Decimal(float) will give you the decimal representation of a floating point number. What you're seeing is the entire raison d'etre for Decimals; floats are binary approximations of (supposedly really large) numbers, converting them to Decimal (or trying to round them etc.) will expose that approximation, and if you're not aware of those internals you'll run into these kinds of suprises.
The only way that this would display with scientific notation is if that value is a float, not an int because ints cannot be displayed in scientific notation: In : df = pd.DataFrame([48726528, 97573906, 69857386, 999999999999999999]) In : df Out: 0 0 48726528 1 97573906 2 69857386 3 999999999999999999

Use string formatting, which gives you all the control you need over the formatting of floating point values: print '= {:.3e} m^3/min'.format(W_ / 1000) The .3 is the precision (3 decimal digits), the e tells the floating point object to use scientific notation. I am trying to convert a program to Python (using numpy and pandas as well) from MATLAB. The input is a (n by 2) array called scaletestmatrix (in this case a 6x2 array). Column one is the x values, which contains some values more than once. Column two is the y values.

Sep 12, 2001 · Scientific notation uses floats, which have only a limited number of significant digits (the number was between 15 and 17, AFAIR) and are stored as a mantissa and an exponent in base2 internally. 10**40 is about 2**132.877123795. So as long as you have less then 133 bits for the mantissa, the computer can only approximate it, the lower bits are ...

I am trying to populate an array with a data set of numbers that are imported as strings. I start by converting them to floats, and then put the floats into an array. After the stage of float conversion, they appear correctly as floats. However, after the stage of insertion into the numpy array, they appear as scientific notation. The code is here:
Scipy (which will be covered in the next post), is of course a major component and another absolutely fantastic library, but I feel these three are the real pillars of scientific Python. So without any ado, let’s get on with the third post in this series on scientific Python and take a look at Pandas.
