An antilog [properly, antilogarithm].  Equivalently, 10 to that power 
(if, as in your example, you are taking logarithms to the base 10);  or 
e to that power (if you are taking natural logarithms), which is also 
called the exponential function, exp( ).

lg10(3) = 0.47712.  In SPSS-speak, 10**(0.47712) = 2.99999

For natural logarithms,  ln(3) = 1.0986,  exp(1.0986) = 2.99996
