  • Log is a mathematical function, suitable for both symbolic and numerical manipulation.
  • Log gives exact rational number results when possible.
  • For certain special arguments, Log automatically evaluates to exact values.
  • Log can be evaluated to arbitrary numerical precision.
  • Log automatically threads over lists.
