[FIXED] Decimal float to int conversion error in python

Issue

I have the following code in python,

x = 0.29
x = int(x*100)
print(x)

It prints 28, and this is causing an infinite loop in my code. How do I resolve this issue? I think this is some machine precision issue. I my program I want the value of int(x*100) to be 29.

Solution

You're encountering a floating-point precision issue, try using the Decimal library which is designed to give better precision with floating-point numbers:

from decimal import Decimal

x = Decimal('0.29')
x = int(x * 100)
print(x)

Should output 29 as you expect.

As per OP comment:

from decimal import Decimal

def get_float():
    return 0.29  # Simulating the function that returns a float

x = int(Decimal(str(get_float())) * 100)
print(x)
