MySQL LOG10() function

LOG10() function

MySQL LOG10() returns the natural logarithm of a number to the base 10. The equivalent expression of LOG10(N) is LOG(10,N).

This function is useful in -

• This is useful in scenarios where the data naturally aligns with the decimal system, such as in financial calculations, measurements, and scientific experiments.
• The LOG10() function is essential in chemistry for calculating the pH of a solution, which is a measure of its acidity or basicity. The pH scale is logarithmic in base 10.
• LOG10() is used in acoustics to calculate the decibel level, a logarithmic scale used to quantify the intensity of sound.
• Base-10 logarithms are used to compare the relative sizes or magnitudes of numbers.
• In engineering fields like electrical engineering, civil engineering, and mechanical engineering, base-10 logarithms are frequently used in calculations involving quantities like voltage, power, and structural properties.
• The LOG10() function is used to convert numbers from scientific notation (exponential form) to standard decimal notation.
