Forcing to make floating point calculations

You may force a floating point division like any of these, no matter if anything is imported from __future__ :

print val1 / (val2 + 0.0)
print (val1 + 0.0) / val2
print float(val1) / val2
print val1 / float(val2)

from __future__ import division

print 1 / 3
print 1 // 3

If your users are entering values anyway, then presumably you are converting the values to int float 相反。

val1 = float(raw_input())
val2 = float(raw_input())
print val1/val2
