Note that float can approximately represent the latter and still smaller values - it's just about 7 decimals of precision after the first nonzero digit! If you're going to use a fixed epsilon, you should really …

Dec 14, 2015 · Just wondering over here, what is the point of having a variable store an infinite value in a program? Is there any actual use and is there any case where it would be preferable to use foo = …

Apr 11, 2012 · The values for the float data type come from having 32 bits in total to represent the number which are allocated like this: 1 bit: sign bit 8 bits: exponent p 23 bits: mantissa The exponent …

Why do some numbers lose accuracy when stored as floating point numbers? For example, the decimal number 9.2 can be expressed exactly as a ratio of two decimal integers (92/10), both of which can be

Jun 29, 2009 · What are the differences between numeric, float and decimal datatypes and which should be used in which situations? For any kind of financial transaction (e.g. for salary field), which one is …

[float(i) for i in lst] to be precise, it creates a new list with float values. Unlike the map approach it will work in py3k.

For a given IEEE-754 floating point number X, if 2^E <= abs(X) < 2^(E+1) then the distance from X to the next largest representable floating point number (epsilon) is: epsilon = 2^(E-52) % For a 64-bit …

The code review tool I use complains with the below when I start comparing two float values using equality operator. What is the correct way and how to do it? Is there a helper function (commons-*)...
