So, I wrote this code:

“num = 0.0

while True:

streq = input()

if streq == “p”:

num += 0.1

print(“Number is: {}”.format(num))”

here, every time I type p and press enter, num is supposed to be multiplied by 0.1 and printed on the screen, but after doing this a few times, it starts printing some weird numbers:

“p

Number is: 0.1

p

Number is: 0.2

p

Number is: 0.30000000000000004

p

Number is: 0.4

p

Number is: 0.5

p

Number is: 0.6

p

Number is: 0.7

p

Number is: 0.7999999999999999

p

Number is: 0.8999999999999999

p

Number is: 0.9999999999999999

p

Number is: 1.0999999999999999

p

Number is: 1.2

p

Number is: 1.3

p

Number is: 1.4000000000000001

p

Number is: 1.5000000000000002

p

Number is: 1.6000000000000003

p

Number is: 1.7000000000000004

p

Number is: 1.8000000000000005

p

Number is: 1.9000000000000006

p

Number is: 2.0000000000000004”

what am I doing wrong? please help.
