import math
​
# Logarithm with base 10:
#                 x            y
print(math.log10( 1     ) )  # 0
print(math.log10( 3     ) )  # 0.47712125471966244
print(math.log10( 10    ) )  # 1
print(math.log10( 100   ) )  # 2
print(math.log10( 1000  ) )  # 3
​
print(math.log10(-1))        # ValueError
print(math.log10(0))         # ValueError
print(math.log10(math.inf))  # inf

Syntax	xxxxxxxxxx 1 math.log10(x)
Parameters	`x` - double value in the range `0` to `infinity`.
Result	`number` value calculated as log_10(x) mathematical function. If `x` is negative it returns `ValueError`. If `x` is equal to `0` it returns `ValueError`. If `x` is equal to `infinity` it returns `infinity`.
Description	`log10` is a method that takes one parameter and returns an approximation of the log_10(x) mathematical function (logarithm with base `10`). `log10` is called a common logarithm.
