Compute logarithm of A to the base B.
[SPU LOG A B OUT Y]
In | Out | Description |
---|---|---|
Anumber, Bnumber | Ynumber | Y = logB(A) |
Avector, Bnumber | Yvector | Y[i] = logB(A[i]) |
Avector, Bvector | Yvector | Y[i] = logB[i](A[i]) |
with: 0 ≤ i < length of Avector
note:
- The logarithm is computed using the following formula:
y = ln(a)/ln(b)
.
ln
is the natural logarithm and botha
andb
must be greater than zero- See also
