Prints out a "3" instead of a "4" on the second-to-last line and "3.999998" instead of "4.000000"
Hello, Pi Pico!
0.004 = 0.004
1000 = 1000
0.004 * 1000 = 4.0
int(0.004 * 1000) = 3
"%f" % (0.004 * 1000) = 3.999998
The crux of the issue is that int(0.004 * 1000) prints out "3" instead of "4".
It's unclear to me why it does this, both numbers have pretty simple representations in IEEE754 (using https://www.h-schmidt.net/FloatConverter/IEEE754.html, 0.004 is actually 0.0040000001899898052215576171875, 1000 is actually 1000)
