I’m first converting the Datatype of the column to float64 df[data_column] = df[data_column].astype("float64") After that… Read More How to prevent Floating-Point errors with Pandas

How to use big.js?

From the examples of big.js they show this example 0.3 – 0.1 // 0.19999999999999998 x = new Big(0.3) x.minus(0.1) // "0.2" x // "0.3" x.div(y).plus(z).times(9).minus(‘1.234567801234567e+8’).plus(976.54321).div(‘2598.11772’) Which is a very simple example. In my case I would like to calculate res = a + (b / c) + (d + 1) / (e * f *… Read More How to use big.js?

Not able to 'numpy.float64' to int in python

I am trying to convert ‘numpy.float64’ to float to do this: ax.get_ylim()[0].astype(float) Which prints out -2.25 But when I check with type(ax.get_ylim()[0].astype(float)) it is printing out numpy.float64. Why is it not changing the data type? >Solution : Can you try the following: float(ax.get_ylim()[0])
