Summation based benchmark for calculators

[ijabbott]

I bought a 2nd hand Texas Instruments TI-57 II from eBay. It's a nice looking calculator in a nice case, but is a bit on the slow side. According to datamath.org, mine is the TI-57 II (1986) variant.

max = 10
~ 39s - TI-57 II - keystroke program (DSZ loop), 13.711835

max = 100
~ 419s - TI-57 II - keystroke program (DSZ loop), 139.29719

For what it's worth, the tests were done in degrees mode with the following program:

Code:

00 STO 0
01 ON/C
02 LBL 0
03 +
04 RCL 0
05 INV tan
06 sin
07 INV lnx
08 INV y^x
09 3
10 2nd Dsz
11 GTO 0
12 =
13 R/S
14 RST
