Python log10

by

The Python log10 function is one of the Python Math functions that calculate the logarithmic value of a given number of base 10. In this section, we discuss how to use log10 function in Python Programming language with example.

This Python log10 function is more accurate than math.log(x, 10). The syntax of the log10 Function in Python Programming Language is

math.log10(number);

Number: A valid numeric expression and

  • If the number argument is a positive number, the log10 function returns the output.
  • If the number argument is Zero or Negative number, log10 function returns ValueError.
  • And if it is not a number, log10 function return TypeError.

Python log10 Function Example

The Python log10 Function calculates the logarithmic value of a given number of base 10. In this log10 example, We find the base 10 logarithmic value of different data types and display the output.

# Python LOG10 Function

import math

Tup = (1, 2, 3, -4 , 5) # Tuple Declaration
Lis = [-1, 2, -3.5, -4 , 5] # List Declaration

print('Logarithm value of Positive Number = %.2f' %math.log10(1))
print('Logarithm value of Positive Decimal = %.2f' %math.log10(2.5))

print('Logarithm value of Tuple Item = %.2f' %math.log10(Tup[2]))
print('Logarithm value of List Item = %.2f' %math.log10(Lis[4]))

print('Logarithm value of Multiple Number = %.2f' %math.log10(2 + 7 - 5))
print('Logarithm value of String Number = ', math.log10('Hello'))

OUTPUT

Python LOG10 Function

ANALYSIS

  1. Within the first two statements, We used the log10 Function directly on Positive integer and Decimal values.
  2. Next two statements, We used the log10 Function on Python Tuple and Python List items. If you observe the above Python screenshot, this Math function is calculating the logarithm value of base 10.
  3. Next statement, We tried log10 Function directly on multiple values
  4. Next, We tried log10 Function on the String value, and it returns TypeError: a float is required as output
  5. Then, We tried log10 Function on Negative value. As we said before, this is returning ValueError: math domain error as output
  6. Last, We tried log10 Function on Zero value. As we said before, this is returning ValueError: math domain error as output.
