New issue 2110: simple euler method example failing to converge
https://bitbucket.org/pypy/pypy/issues/2110/simple-euler-method-example-failing-to
zorg24:
This is a very naive attempt at performing at integrating y'=1/3x^2 over [0,1]
with y(0)=0 using Euler's method, however for inc between 0.6e-7 and 1.3e-7 (I
didn't try to be any more precise) it is failing to converge on my machine. For
other values it runs quite fast as would be expected, also noteworthy is that
it runs fine if line 6 is commented out.
```
#!python
def main():
inc=1e-7
result=0.0
i=0.0
while (i <= 1.0):
result += inc * (1.0/3.0 * i * i)
i += inc
print(result)
main()
```
