hi
I don't know what does the arithmetic say!
The result from a is 1000, then the result from b is 6.
I have optimized a system for a long time, but i find out i must
optimize all aspects, just a aspect isn't work.
I want to know arithmetic's theory.
a.
long endPoints = (1000 + 1000 + 1000 + 1000 + 1000) / 5;
if(endPoints > 6208L)
endPoints = 6208L;
long halfEndPoints = endPoints / 2L;
long l2 = endPoints - halfEndPoints;
long l3 = 1L;
l3 = 1000L*1000L*1000L*1000L*1000L;
f(l3 != 0L)
while(halfEndPoints > 0L)
{
if(l2 * l2 * l2 * l2 * l2 > l3)
endPoints = l2;
else
halfEndPoints /= 2L;
l2 = endPoints - halfEndPoints;
}
else
endPoints = 0L;
System.out.println("endPoints: " + endPoints);
result : 1000
b.
long endPoints = (6000 + 1 + 1 + 1 + 1) / 5;
if(endPoints > 6208L)
endPoints = 6208L;
long halfEndPoints = endPoints / 2L;
long l2 = endPoints - halfEndPoints;
long l3 = 1L;
l3 = 6000L*1L*1L*1L*1L;
f(l3 != 0L)
while(halfEndPoints > 0L)
{
if(l2 * l2 * l2 * l2 * l2 > l3)
endPoints = l2;
else
halfEndPoints /= 2L;
l2 = endPoints - halfEndPoints;
}
else
endPoints = 0L;
System.out.println("endPoints: " + endPoints);
result : 6
Thanks and Regards,
