No. 15% is *not* always 0.15. However, 15% IS always 15/100 x n, where n is any value between -infinity and +infinity. What we're really debating here is calculator behavior here. There are other "understood" conventions in the world of calculators besides this percent thing, such as when multiplying by a constant; each subsequent time you hit the = key, you multiply again by that constant. You didn't have to again enter the X key and that constant, because the calculator is programmed to operate that way. I'm pretty sure that you guys truly understand what this debate is about, unless you're just yanking our chains.. you wouldn't be doing that, would you? ;-) nk On Nov 27, 2005, at 11:45 PM, John Baltutis wrote: > That interpretation assumes that 28.05 + 15% implies 28.05 * (1 + > 0.15). > Why? 15% is always 0.15 if you don't indicate "of something else"; > whereas, > 15% of x is always 0.15 * x. -------------- next part -------------- An HTML attachment was scrubbed...
