objectChecksum

objectChecksum(vector, [prev])

vector is a vector that is used for calculating checksums.

prev is an integer. If the vector is too long, the checksum can be computed iteratively by specifying prev which represents the checksum of the previous segment of data during iteration.

Calculate the checksum of a vector. The result is an integer. It is often used to verify data integrity.

print objectChecksum(take(`A`B`C, 10))
// output
-268298654

print objectChecksum(2.3 6.5 7.8)
// output
-430996932

//calculate checksum section by section
print objectChecksum(1..15)
// output
-1877567753

t0 = objectChecksum(1..5)
t1 = objectChecksum(6..10, t0)
t2 = objectChecksum(11..15, t1)
print t2
// output
-1877567753
