I went to do a calculation in Python 2.7 and I was scared to see the result:
val = 1 / 16
print(val); # 0
Example on IDEONE
That is, when we make a division where the number divided is less than the divisor, the result returned is zero.
How do I get the result in float ?
Why does Python behave this way?
Division of integers, returns integer. Make one of them type float :
val = float(1) / 16
print(val);
#saida: 0.0625
Or force the change of the behavior of the / operator so that it is equal to python3.x :
from __future__ import division
val = 1/16
print(val);
#saida: 0.0625
In almost every language the division of integers results in an integer. To ensure that the operation results in a floating-point number, you must have at least one of the operands as float , so you need to place a decimal point in one of them. This is strong typing .
val = 1.0 / 16
print(val); # 0
