Re: Using BV exp(), log() for numerical compression ,wrong result ?

I suppose you do realise that you can make one or both axes of a plot logarithmic. You can also plot, for example log(V(out) on a log axis, so get a log-log scale, using waveform arithmetic.

Hi, Andy:


Before your explanation, I didn't notice "complex logarithm" is a special case, maybe not supposed to be supported by any SPICE.

About the compression application, I didn't really have the complete idea, maybe it would be like the,....
For example, when someone reading a book, the edge on every page often empty, and be used to sketch some thing on, some graphs/pictures to decorate the layout of the page. They often are not the primary parts.

To analogy, if there are some main data, which typically are numerical values, and has its general scale on the range of greater than 0.01, though its format could support to very least 1e^-16, or some, such that, maybe I could merge those loged numbers secretly into the "main data", and leak .... to somewhere who concern it, without interference others who typically don't care those smaller values which is under 0.01.

Just some ignorant ideas. I didn't implement it yet.

Best regards.
