how do i round up the the nearest whole number without importing math. Thanks

Question

how do i round up the the nearest whole number without importing math. i did y + 0.999 . it did work but doesn't seem the right way.

numpaint = int(input())
canv = 40
pt = 5
x = (numpaint * pt) + canv
y = (x * 1.1) # 10%
y = y + 0.999 # to round up?
print(int(y))

Answer 1

Mr Steven Kervick🇺🇦 there is a way to get the smallest floating point number, which is called epsilon. Use that to add *almost* 1.0, but just enough under 1.0 that it won't round up an exact integer.

import sys
rup = 1.0 - sys.float_info.epsilon
...
y = int(y + rup) # to round up

Answer 2

Won't truncating and adding 1 work?

x = #some_float
n = 1 + int(x)

There may be the issue that x is already integer. Then rounding should not yield x+1 i suppose. Then check first int(x) == x.

Answer 3

You can use the built-in function round()

Examples:

round(1.1)
output: 1

round(1.5)
output: 2
