double      log10( Integral arg );
(since C++11)

Computes the common (base 10) logarithm of arg.

[edit] Parameters

arg - value of floating-point or Integral type

[edit] Return value

Base 10 logarithm of arg.

Domain error occurs if arg is negative. NAN is returned in that case.

Range error occurs if arg is 0. -HUGE_VAL is returned in that case.
