------------------------------------
Summary: Fix Pi Estimator Example
Key: HAMA-905
URL: https://issues.apache.org/jira/browse/HAMA-905
Project: Hama
Issue Type: Bug
Components: examples
Affects Versions: 0.6.4
Reporter: Martin Illecker
Priority: Minor
Fix For: 0.7.0
*Fix Pi Estimator Example*
I think we should skip the *sqrt* method in \[1] and change the if condition
based on formula 6 on page 2 in \[2].
{code}
IF (x^2 + y^2 <= 1) THEN
SUM = SUM +1
END IF
{code}
Because the Equation of the Circle is
{code}
x^2 + y^2 = r^2
x^2 + y^2 = 1 (with r=1 in unit circle)
-> (x^2 + y^2 <= 1)
{code}
Thanks!
