#144551 - ... floating point again... Responding to: ???'s previous message |
Jerson Fernandes said:
Again, you need the lattitude and longitude to achieve what you want and lots of floating point calculations. Ah, that floating point again. I doubt it is really floating point which is necessary here. Trigonometric functions, no doubt. Multiple precision, maybe. But I doubt there is really a need for numbers in several (tens) orders of magnitude, to justify the semilogaritmic notation float in fact is. Maybe this topic deserves more attention. Would a "fixed point" trigono/logexp library be of any use? JW |
