Common mistakes

  • ⚠️ Trying to calculate log of zero or negative numbers (undefined)
  • ⚠️ Using base 1 which is mathematically invalid for logarithms
  • ⚠️ Confusing log base 10 with natural log (base e)

Worked example

Calculate log base 10 of 1000 for pH or Richter scale calculations

The resultado ({resultado}) is the exponent to which base_log must be raised to get número; log_natural uses base e (Euler's number).
