How fast is 8-bit 6502 CPU on famicom clone (SB2000), check this out

This posts uses the following F-BASIC to compute approximation of PI, however, when N=100, it takes even a couple of seconds.

10 N=100
20 C=0
30 FOR I=1 TO N
40 X=RND(1000)/1000.0
50 Y=RND(1000)/1000.0
60 IF X*X+Y*Y<=1.0 THEN C=C+1
70 NEXT I
80 PRINT 4.0*C/N

F-BASIC is really really slow, because of 1. it is 8-bit, 2, it is an interpret language (not assembly).
