Here are some more Savage benchmark results for the ST (forgive me if they were
already on the net):

System        CPU / FPP      MHz       LANGUAGE          Seconds    Error
------------------------------------------------------------------------------
Atari ST      68000/-----    8.0  ProFortran (single prec.)  16    2.7 E+02
Atari ST      68000/-----    8.0  ProFortran (double prec.)  52    3.1 E-07
Atari ST      68000/-----    8.0  GfA-Basic (Interpreter)    15.7  3.7 E-05
Atari ST      68000/-----    8.0  GfA-Basic (Compiler)       13.9  3.7 E-05
Atari ST      68000/-----    8.0  Omikron-Basic (single prec.) 11  0.6 E 00
Atari ST      68000/-----    8.0  Omikron-Basic (double prec.) 76  1.1 E-09 (!)

Conclusion: If you want to do number-crunching on the Atari ST, try BASIC !
Here is the GfA-Basic program that was used:

Startingtime=Timer
A=1
For I=1 To 2499
  A=Tan(Atn(Exp(Log(Sqr(A*A)))))+1
Next I
Print (Timer-Startingtime)/200'"seconds","Error :"'A-2500
