Mojo function
log1p
log1p(value: Symbol) -> Symbol
Computes the elementwise logarithm of 1 plus a symbolic tensor.
Creates a new op node to compute the elementwise log1p of a symbolic tensor and adds it to the graph, returning the symbolic result.
The log1p
function is defined as log1p(x) = log(1 + x)
, where log()
is the natural logarithm.
Using log1p(x)
rather than computing log(1 + x)
can give greater
numerical precision results.
log(x)
is undefined for x <= 0
for real numbers. Complex numbers
are currently unsupported.
Args:
- βvalue (
Symbol
): The symbolic tensor to use as the input to the log1p computation.
Returns:
A new symbolic tensor value representing the output of the absolute value computation.
Raises:
If the symbol doesn't represent a tensor value.
