One practical way to understand the function of the natural logarithm is to put in the context of compound interest. That is the interest that is calculated on both the principal and the accumulated interest. We still don't know what the exact result is, so we take the exponent of both sides of the equation above with some change on the right side. You may notice that even though the frequency of compounding reaches an unusually high number, the value of (1 + r/m)ᵐ (which is the multiplier of your initial deposit) doesn't increase very much. Instead, it becomes somewhat stable: it's approaching a unique value already mentioned above, e ≈ 2.718281. The new computational procedure was instrumental in the field of astronomy. Napier's scientific activities coincided with the era of new developments in astrophysics. As a result, many astronomers were struggling with endless calculations to detect the position of the planets using Copernicus's theory of the solar system. Johannes Kepler, at the time working on his famous laws of planetary motions, was among them.

Following the formula, input the values of a and b in the corresponding fields. These can be integers, decimals, etc.

Step 2:

If you want to compute a number's natural logarithm, you need to choose a base that is approximately equal to 2.718281. Conventionally this number is symbolized by e, named after Leonard Euler, who defined its value in 1731. Accordingly, the logarithm can be represented as logₑx, but traditionally it is denoted with the symbol ln(x). You might also see log(x), which also refers to the same function, especially in finance and economics. Therefore, y = logₑx = ln(x) which is equivalent to x = eʸ = exp(y).

To make your lives easier, we've prepared a nice step-by-step instruction on how to use Omni's decimal calculator. lg ( 5.89 × 4.73 ) = lg ( 5.89 ) + lg ( 4.73 ) ≅ 0.770115 + 0.6748611 \text{lg}(5.89 \times 4.73) =\text{lg}(5.89) + \text{lg}(4.73) ≅ 0.770115 + 0.6748611 lg ( 5.89 × 4.73 ) = lg ( 5.89 ) + lg ( 4.73 ) ≅ 0.770115 + 0.6748611 times 4.73 ≅ 10 The other popular form of logarithm is the common logarithm with the base of 10, log₁₀x, which is conventionally denoted as lg(x). It is also known as the decimal logarithm, the decadic logarithm, the standard logarithm, or the Briggsian logarithm, named after Henry Briggs, an English mathematician who developed its use.
