# log10

## Returns the log base 10 of n.

**Syntax:**

log10(n);

Argument |
Description |

n |
The input value. |

**Returns:** Real

### Description

This function is similar to the `log2(n)` function, only that
`log10(n)` gets the number of 10's that we need to multiply
together to get n. So `log10(100)` returns 2, as multiplying
10 by itself gives 100, `log10(1000)` returns 3 as
10x10x10=1000 etc... The number does *not* have to be
divisible by ten, however, but this will still return an
appropriate value, for example if we have `log10(101)` we
get 2.00432137... which is how many times you could divide 101 by
10.

**Example:**

logval = log10(num);

The above code gets the `log10` of the value stored in
"num".
