- Tran is a benchmark program for measuring the speed of transcendental
- mathematical operations. To use it you type "tran loops" where loops is
- the number of loops of each test that you want. Choose a big enough
- number of loops so that the slowest test takes at least ten seconds.
- I suggest the following number of loops as likely to be right:
-
- Processor DX SX or FPU disabled
- 486-33 800000 3000
- 486-66 1600000 6000
- 486-100 2000000 10000

- For my Ocean Hippo DCA-2 motherboard and an AMD 486DX-100 CPU I get:
-
- 2000000 in 11.37 seconds for 175901 sin/s
- 2000000 in 11.09 seconds for 180342 cos/s
- 2000000 in 14.44 seconds for 138504 tan/s
- 2000000 in 13.24 seconds for 151057 asin/s
- 2000000 in 14.17 seconds for 141143 acos/s
- 2000000 in 10.94 seconds for 182815 atan/s
- 2000000 in 10.60 seconds for 188679 log/s
- 2000000 in 10.54 seconds for 189753 log10/s

- With FPU disabled by "set NO87=NoFPU"
-
- 100000 in 9.99 seconds for 10010 sin/s
- 100000 in 10.27 seconds for 9737 cos/s
- 100000 in 11.97 seconds for 8354 tan/s
- 100000 in 22.91 seconds for 4364 asin/s
- 100000 in 24.71 seconds for 4046 acos/s
- 100000 in 18.40 seconds for 5434 atan/s
- 100000 in 16.43 seconds for 6086 log/s
- 100000 in 16.58 seconds for 6031 log10/s
