Forcing floating point calculation

Question

There is some way in IronPython to force an expression containing integer values ​​to evaluate as a floating point. For example, I would like the expression

1/3

estimated as

1./3. 

with the result 0.333 ...

I need this to make a simple runtime expression calculator in a C # project using IronPython. I cannot get users to enter an expression with end decimal points.

Answer 1

You can force floating point division, like any of them, regardless of whether anything is imported from __future__:

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

Answer 2

from __future__ import division

print 1 / 3
print 1 // 3

Answer 3

, , , int s. float.

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