Hi,
there may be a serious error in python's int() function:
print int(float(2.8/0.1))
yields
27
instead of 28!!
I am using Python Python 2.7.6, GCC 4.8.2 on Linux Ubuntu.
Is that known?
Best,
Martin
I have a similar question, so I post my message here.
Hope this will not annoy the OP
Is it sure that the square root of a square number is always
an integer ?
I would not like to get a result as 345.99999999
from math import sqrt
sqrt(16)
4.0
sqrt(16).is_integer()
True
for n in range(1000000):
... if not sqrt(n**2).is_integer():
... print(sqrt(n**2))
it seems to work ... but does it work for all integers ?
