Rounding errors of values when compared to other sources

[rajkolli03]

There are quite a lot of rounding errors for calculations when compared to other sources like excel. For example while extending this library, I found that a particular calculation returns -29.45736 in Javascript and -29.56 in Excel. This can throw quite a few indicators off.

Can you provide some examples in an excel sheet?

this doesn't look like a rounding error, this is too far off!

anyway sometimes when working with numbers and JS it's worth using https://github.com/MikeMcl/bignumber.js/

@csupnig I'll try to get an Excel to compare the values out.

@csupnig @hems Do you think its worth to run an exercise, an attempt using big.js for calculations?

-29.45736 = -29.4574 = -29.457 = -29.46 = -29.5

Not too far LOL
