output = n*log10(input) + k
 
output = n*log10(input) + k
  
Only handles Float input and output.
+
Args:
 
+
* 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.
