#### double DecibelToNeper(double decibel)

Converts a ratio in Decibel (dB, not representing a power gain, or both compared values are already powers) to Neper (Np).
 return `double` `double` decibel

#### double DecibelToRatio(double decibel)

Given a ratio in Decibel (dB), evaluate the effective ratio.
 return `double` `double` decibel

#### double DecibelToValue(double decibel, double baseValue)

Given a ratio in Decibel (dB) and the fixed base value, evaluate the effective value.
 return `double` `double` decibel `double` baseValue

#### double NeperToDecibel(double neper)

Converts a ration in Neper (Np, not representing a power gain, or both compared values are already powers) to Decibel (dB).
 return `double` `double` neper

#### double NeperToPowerDecibel(double neper)

Convert a ratio in Neper (Np, representing a power gain, while the compared values are not powers, e.g. amplitude, ampère, volts) to Decibel (dB).
Power Decibel indicates that the method takes care of squaring the compared values to get a power gain mesure.
 return `double` `double` neper

Given a ratio in Neper (Np) and the fixed base value, evaluate the effective value.
 return `double` `double` neper `double` baseValue

#### double PowerDecibelToNeper(double decibel)

Convert a ratio in Decibel (dB, representing a power gain, while the compared values are not powers, e.g. amplitude, ampère, volts) to Neper (Np).
Power Decibel indicates that the method takes care of squaring the compared values to get a power gain mesure.
 return `double` `double` decibel

#### double PowerDecibelToRatio(double decibel)

Power Decibel indicates that the method takes care of squaring the compared values to get a power gain mesure.
 return `double` `double` decibel

#### double PowerDecibelToValue(double decibel, double baseValue)

Given a ratio in Decibel (dB, representing a power gain, while the compared values are not powers, e.g. amplitude, ampère, volts) and the fixed base value, evaluate the effective value.
Power Decibel indicates that the method takes care of squaring the compared values to get a power gain mesure.
 return `double` `double` decibel `double` baseValue

#### double RatioToDecibel(double ratio)

Given a ratio, express it in Decibel (dB).
 return `double` `double` ratio

#### double RatioToDecibel(double value, double baseValue)
