Compute the logarithm of x to base 10. Throws DomainError for negative Real arguments.


  1. Calculate the logarithm of a positive number:

    julia> log10(1000)

    This example computes the base 10 logarithm of 1000, which is 3.

  2. Compute the logarithm of a floating-point number:

    julia> log10(3.14)

    It calculates the base 10 logarithm of the floating-point number 3.14.

  3. Handle domain error for negative arguments:
    julia> log10(-10)
    ERROR: DomainError with -10.0:
    log10 will only return a complex result if called with a complex argument. Try log10(Complex(x)).

    The log10 function throws a DomainError when trying to compute the logarithm of a negative real number. The error message suggests using Complex to compute the complex result.

Common mistake example:

julia> log10("Hello")
ERROR: MethodError: no method matching log10(::String)

In this example, the log10 function is used with an unsupported argument type (String). It's important to ensure that the argument passed to log10 is a valid numeric value.
