float       log10f( float arg );

double      log10( double arg );
long double log10l( long double arg );
(since C99)

Computes the common (base 10) logarithm of arg.

Parameters

arg - floating point value

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.
