Format floats with standard json module
I am using the standard json module in python 2.6 to serialize a list of floats. However, I’m getting results like this:
Python float – str – float weirdness
>>> float(str(0.65000000000000002)) 0.65000000000000002 >>> float(str(0.47000000000000003)) 0.46999999999999997 ??? What is going on here? How do I convert 0.47000000000000003 to string and the resultant value back to float? I am using Python 2.5.4 on Windows. Answers: Thank you for visiting the Q&A section on Magenaut.

ValueError: could not convert string to float: id
I’m running the following python script:
Range values to pseudocolor
I have a certain array of floats (in Python) that might range from 0 to 100. I want to create a pseudo-color image so that the colors vary from green (corresponding to 0) to red (100). This is similar to pcolor from matplotlib. However, I do not want to use pcolor.
negative zero in python
I encountered negative zero in output from python; it’s created for example as follows:
Easy pretty printing of floats?
I have a list of floats. If I simply print it, it shows up like this:
Convert floating point number to a certain precision, and then copy to string
I have a floating point number, say 135.12345678910. I want to concatenate that value to a string, but only want 135.123456789. With print, I can easily do this by doing something like:
Testing floating point equality
Is there a function to test floating point approximate equality in python? Something like,
Convert Python strings into floats explicitly using the comma or the point as separators
How can I explicitly tell python to read a decimal number using the point or the comma as a decimal separator? I don’t know the localization settings of the PC that will run my script, and this should not influence my application, I only want to say:
