Common logarithm: log₁₀(n) is the power to which 10 must be raised to equal n. For example, log₁₀(100) = 2.

常见问题

What is a common logarithm?
A common logarithm (log₁₀) is the exponent to which 10 must be raised to produce the given number.
What is log₁₀(1)?
log₁₀(1) = 0, because 10⁰ = 1.
What is log₁₀(10)?
log₁₀(10) = 1, because 10¹ = 10.
How are these values calculated?
Values are computed using the Math.log10 function and rounded to 4 decimal places.
