Casio Calculator Performance Index Report

[toml_12953]

I just got the Casio fx-9860GIII and I put in one of the two standard benchmarks to test it.

The benchmark is located at

https://www.thimet.de/CalcCollection/Cal...mance.html

The Casio scores an index of about 4350. That is a very respectable score, according to the table on the site!

I wrote the benchmark in Python and since the Casio has no internal timer, I timed the calculator with a stopwatch, then adjusted the number of loops so the runtime is 5 seconds. The calculation of the index on the site is only correct for 1 loop. For multiple loops, the formula is

Index = 34 / T * Loops

so on the Casio, since I was able to run 640 loops in 5 seconds, the index is

Index = 34/5*640

which is an index of 4352.0

Here's the Python program I used:

Code:

from math import *
loops=640
for i in range(0,loops):
  r0=10
  while r0>0:
    x=r0
    x+=1
    x-=4.567E-4
    x+=70
    x-=69
    x*=7
    x/=11
    r0-=1
  x=log(x)
  x=sin(x)
  x=sqrt(x)
  x=sqrt(x)
print(x)
print("Index =",34/5*loops)
