The **`log10()` function** in R uses base 10 to calculate the logarithm of a number.

Figure 1 below shows the mathematical representation of the `log10()` function and the corresponding representation in R.

> **R** is a programming language based on *statistical computing* and *graphics.*

# 
#  Syntax

---
```r
log10(number)
```
# 
## Parameter

This function requires a number whose logarithm base 10 must be calculated, and it must be greater than zero.

* If the number is `zero`, then this function outputs `-Inf`.

* If the number is `negative`, this function outputs `NaN` along with a warning message.
##
## Return value
`log10()` uses base 10 to return the logarithm of a number.

# 
## Code

The following example shows how to use the `log10()` function in R:

a <- log10(10);
print(paste0("log10(10): ", a))

b <- log10(2);
print(paste0("log10(2): ", b))

c <- log10(15.2);
print(paste0("log10(15.2): ", c))

#error outputs
d <- log10(0);
print(paste0("log10(0): ", d))

e <- log10(-1);
print(paste0("log10(-1): ", e))

How to calculate the log10() of a value in R

log10() in R calculates the base-10 logarithm. It requires a positive number and returns -Inf for zero and NaN for negatives.
