LOG10 intrinsic function
Standard: F77 F90 F95 F2003 F2008
Example Program
LOG10 ( X )

X : Real, greater than zero;

Result : Same type and kind as X.
The value of the result is an approximation to the common logarithm (base 10) of X. Like many intrinsic functions, this is elemental; the result has the same shape as X, with the operation being applied elementwise.
