Create a new logarithm calculation instance.
Create a new logarithm calculation instance. This will hold the pre-calculated log values for a given base and a table size depending on a given mantissa quantization.
the logarithm base (e.g. 2 for log duals, 10 for decibels calculations, Math.E for natural log)
the quantization, the number of bits to remove from the mantissa. for q = 11, the table storage requires 32 KB.
