Summary: Bug In Python
Initial Comment:
We are trying to convert a string value of "4.02" into a
interger value multipled by 100.
Eg:
Int(float("4.02")*100)
I think this should return 402 but returns 401
If i replace "4.02" with "4.04, it should return 404 and it
does
Every other number from 4.02 returns an incorrect value.
4.02
4.06
4.10
4.14
etc etc
Can someone help this is driving me mad
Cheers JastheAce

This is just one of the many joys of floating point
arithmetic. See Appendix B in the tutorial for a hint about
what is going on.
To get the results you want, run round(x,0) before applying
int().
