Does anyone know how to convert int to float.
For some reason, it keeps on printing 0. I want it to print a specific decimal.
sum = 144 women_onboard = 314 proportion_womenclass3_survived = sum / np.size(women_onboard) print 'Proportion of women in class3 who survived is %s' % proportion_womenclass3_survived 6 Answers
To convert an integer to a float in Python you can use the following:
float_version = float(int_version) The reason you are getting 0 is that Python 2 returns an integer if the mathematical operation (here a division) is between two integers. So while the division of 144 by 314 is 0.45~~~, Python converts this to integer and returns just the 0 by eliminating all numbers after the decimal point.
Alternatively you can convert one of the numbers in any operation to a float since an operation between a float and an integer would return a float. In your case you could write float(144)/314 or 144/float(314). Another, less generic code, is to say 144.0/314. Here 144.0 is a float so it’s the same thing.
Other than John's answer, you could also make one of the variable float, and the result will yield float.
>>> 144 / 314.0 0.4585987261146497 In Python 3 this is the default behavior, but if you aren't using that you can import division like so:
>>> from __future__ import division >>> 144/314 0.4585987261146497 Alternatively you can cast one of the variables to a float when doing your division which will do the same thing
sum = 144 women_onboard = 314 proportion_womenclass3_survived = sum / float(np.size(women_onboard)) You can just multiply 1.0
>>> 1.0*144/314 0.4585987261146497 You can literally convert it into float using:
float_value = float(integer_value) Likewise, you can convert an integer back to float datatype with:
integer_value = int(float_value) Hope it helped. I advice you to read "Build-In Functions of Python" at this link:
The answers provided above are absolutely correct and worth to read but I just wanted to give a straight forward answer to the question.
The question asked is just a type conversion question and here its conversion from int data type to float data type and for that you can do it by the function :
float()
