Defined in header <cmath>
float       log10( float arg );
double      log10( double arg );
long double log10( long double arg );
double      log10( Integral arg );		(since C++11)

Computes the common (base 10) logarithm of arg.

[edit] Parameters

arg

-

floating point value

[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.
