Support for engineering notation display.

[mofosyne]

Is there some configuration to allow for engineering notation?

Ergo instead of displaying as 5e7, it would be in 50e6 ? Basically to the power of 3, which is convenient when dealing with SI units.

This isn't yet supported but will would a nice new formatting option. We could call it {notation: 'engineer'}.

@mofosyne Displaying 5e7 is closer to scientific notation standard, whereas 50e6 is not. Technically it should be 5.0e7.

Well, some calculators support "Engineering Notation" which does things in powers of 3s.

I'm not saying to replace scientific notation, but rather support "Engineering Notation" mode for those of us who rather not have to do mental conversion to get to micro, nano, pico meters etc... Which these physical calculators did think is valuable enough to include as a feature.

Which the same site you mentioned, also mentioned engineering notation: http://www.purplemath.com/modules/exponent4.htm

Ah, gotcha! This would be a great feature to add.

Hey there, I'd like to take a stab at this - started it here:
https://github.com/johnmarinelli/mathjs/tree/issue457

should have something to show within a few days!

Thanks John!

@johnmarinelli what do you think, should we call the notation option {notation: 'engineer'} or {notation: 'engineering'}? I think I may like the shorter one better.

[mofosyne]

In general speech, I would say: "engineering notation" vs "scientific
notation"

So try "Engineering" for the notation key field.

@josdejong I opted to use {notation: 'engineering'}; I figure that it's the idiomatic way to say it. PR here: #519

[josdejong]

@johnmarinelli yes makes sense, lets go for engineering.

Oh @johnmarinelli is your commit ready to be pulled? I noticed its 243 commits behind josdejong:master which might cause possible conflict when merging

[mofosyne]

Looks like it's all merged in now. Closing.
