Log Node
Description
Returns the logarithm of input In. Log is the inverse operation to the Exponential Node.
For example, the result of a base-2 Exponential using an input value of 3 is 8.
Therefore the result of a base-2 Log using an input value of 8 is 3.
The logarithmic base can be switched between base-e, base-2 and base-10 from the Base dropdown on the node.

Generated Code Example
The following example code represents one possible outcome of this node per Base mode.
Base E
void Unity_Log_float4(float4 In, out float4 Out)
{
Out = log(In);
}
Base 2
void Unity_Log2_float4(float4 In, out float4 Out)
{
Out = log2(In);
}
Base 10
void Unity_Log10_float4(float4 In, out float4 Out)
{
Out = log10(In);
}
