I have a question concerning the numerical speed of Mathematica:

I performed the following calculation

x=0.3;Print[x]; Do[x=x*1.003456,{i,1,1000000}];Print[x]

with Mathematica, it took about 150 seconds.

The same calculation is performed by TurboPascal in 0.4 seconds.

I guess that the difference is caused by the working precision. Does
anyone know what is the reason for this long duration and how it can be
