LOG10

LOG10(expr)

Description

The LOG10 function is used to calculate the base-10 logarithm of a given numerical expression expr. This function is very useful when dealing with exponential data, as it can help quickly understand the growth rate and scale of the data.

Parameter Description

• expr (double type): The numerical expression for which the logarithm needs to be calculated.

Return Result

Returns the calculation result as a double type.

Usage Example

1. Calculate the base-10 logarithm of 100:

SELECT LOG10(100);

Results:

2.0

2. Calculate the base-10 logarithm of 1000 and compare it with common logarithms:

SELECT LOG10(1000);

Results:

3.0

3. Calculate the base-10 logarithm of different values and observe the changes in the logarithm values:

SELECT LOG10(1), LOG10(10), LOG10(100), LOG10(1000);

Results:

0.0 1.0 2.0 3.0

4. Calculate the base-10 logarithm of consecutive integers to understand the rate of numerical growth:

SELECT LOG10(1), LOG10(10), LOG10(100), LOG10(1000), LOG10(10000);

Results:

0.0 1.0 2.0 3.0 4.0

By the above example, it can be observed that as the value increases, the logarithm base 10 of the value also increases. The LOG10 function has a wide range of applications in data analysis and processing, helping users quickly understand the scale and growth rate of the data.
