[Solved]. Re: Multiples of 3 & 5 in python

Question

[Solved]
Why does this code return the numbers with the period?
import numpy as np

numbers = np.array([])

for i in range(1,100):
if i % 3 == 0 and i % 5 == 0:
numbers = np.append(numbers, i)
print(numbers)

Returns:
[15. 30. 45. 60. 75. 90.]
and not

[15 30 45 60 75 90]
like this code does:

x = np.arange(1,100)
print(x[(x%3==0)&(x%5==0)])

Answer 1

Numpy formats floating point numbers like that. 100. actually means 100.00

try

print(numbers.astype(int))
