output = n*log10(input) + k
output = n*log10(input) + k
Only handles Float input and output.
* n - Scalar multiplicative constant
This block handles null and negative samples by using, for each sample, the max between the sample and the minimum positive value for a float32 number.
* vlen - Input vector length
* k - Scalar additive constant
== Parameters ==
; n
: Scalar multiplicative constant
; vlen
: Input vector length
; k
: Scalar additive constant
== Example Flowgraph ==
This flowgraph shows how the Log10 basic usage. The negative value handling can be seen.
