### Common logarithm (base 10) - MATLAB log10

• Y = log10(X) returns the common logarithm of each element in array X.The function accepts both real and complex inputs. For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf,Inf).For complex and negative real values of X, the log10 function returns complex values

Our professional services, testing methods, equipment and personnel can offer your business customized research and reporting including validation studies, to fit the needs of your operations
• In mathematics, the logarithm is the inverse function to exponentiation.That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.In the simplest case, the logarithm counts the number of occurrences of the same factor in repeated multiplication; e.g., since 1000 = 10 × 10 × 10 = 10 3, the logarithm base.

For complex-valued input, log10 is a complex analytical function that has a branch cut [-inf, 0] and is continuous from above on it. log10 handles the floating-point negative zero as an infinitesimal negative number, conforming to the C99 standard. References. About Log Base 10 Calculator . The Log Base 10 Calculator is used to calculate the log base 10 of a number x, which is generally written as lg(x) or log 10 (x). Log Base 1 The concept of a logarithm is simple, but it's a little difficult to put into words. A logarithm is the number of times you have to multiply a number by itself to get another number In mathematics, the common logarithm is the logarithm with base 10. It is also known as the decadic logarithm and as the decimal logarithm, named after its base, or Briggsian logarithm, after Henry Briggs, an English mathematician who pioneered its use, as well as standard logarithm.Historically, it was known as logarithmus decimalis or logarithmus decadis
