## What does log10 mean in C?

Common Logarithm

In the C Programming Language, the log10 function returns the logarithm of x to the base of 10.

## What does log to the base 10 mean?

Log base 10, also known as the common logarithm or decadic logarithm, is the logarithm to the base 10. The common logarithm of x is the power to which the number 10 must be raised to obtain the value x. For example, the common logarithm of 10 is 1, the common logarithm of 100 is 2 and the common logarithm of 1000 is 3.

## What is a base 10 log called?

## How do I get LOG10 in C++?

The log10() function in C++ returns the common logarithm (base 10 logarithm) of the argument. This function is defined in header file….log10() Return Value.

x < 0 | nan (Not a Number) |

## Is log always base 10?

The base-10, or “common”, log is popular for historical reasons, and is usually written as “log(x)”. If a log has no base written, you should generally (in algebra classes) assume that the base is 10. The other important log is the “natural”, or base-e, log, denoted as “ln(x)” and usually pronounced as “ell-enn-of-x”.

## Is log and log10 the same thing?

Usually log(x) means the base 10 logarithm; it can, also be written as log10(x) . log10(x) tells you what power you must raise 10 to obtain the number x. 10x is its inverse. ln(x) means the base e logarithm; it can, also be written as loge(x) .
