Thinking about creating an organization for stuff like this so we all can take more equal ownership. Either that or move to @thesassway.

Exponents only work for whole numbers and need to be revised for non integers

At least on windows, sass-math fails bundler update bundle install commands on Rails 4.0.1+ if the version of Compass is ver 1.0 or higher...

In the readme.md and in the sassy-math.rb files, the inverse trigonometric functions, the hyperbolic functions and their inverses take in an argument called $radians or rad. That's a bit misleading.

The inverse trigonometric functions actually take in a number value (restricted to the interval [-1, 1] in the case of sin and cos) and output an angle value in radians. It's precisely the inverse of the direct trigonometric functions, which take in an angle value in radians and return a number (which is a number between -1 and 1 for sin and cos).

The hyperbolic functions are just that, hyperbolic functions. They're not trigonometric functions and they don't fall under trigonometry, but under hyperbolic geometry. Their name is just an analogy. Just like when plotting the points (sin(a), cos(a)), the result is the unit circle (which is why the trigonometric functions are also called circular functions), when plotting the points (sinh(a), cosh(a)), the result is the unit hyperbola.

Calling the argument for such a function $radians or rad doesn't make much sense, since the radian is a unit of angular measure. Both the hyperbolic functions and their inverses take in a number value and return a number value as well (with the domain restrictions corresponding to each).

Still trying to find a complete formula, a lot of the ones I am coming across are simplified or use circular logic. Combining simplified versions should point us in the right direction.

Use an algorithm to compute roots instead of feedback loops. It will be more verbose but less processor intensive and faster.

Sam,

I am playing around with building a test suite for this stuff as I dive in but am having trouble getting the ruby working. Are you building a gem after each change to test? Seems like there should be a better way.

Attached is my work, hoping to tackle random numbers and stuff to get back into this:
scottkellum/sassy-math@f7c3654

Planning on rolling this stuff into modular scale, and this project into Compass.

What are people's thoughts on moving from a "push straight to master" model to a "branch and issue pull request" model? This would help with us stepping on each other's toes and make it easier to keep track of discrete pieces to be worked on.
Thoughts?

Hi, is it possible to add this function to sassy-math?

Turn into Compass Plugin.

NOTE — Compass has trig functions built in so leveraging that in the compass-specific build: http://compass-style.org/reference/compass/helpers/trig/

exponent(20, $pi) will crash...

hi,

is it possible to use a prefix for functions in order to avoid conflicts with other frameworks?

thanks!

Ready to make this public soon? Lets just clean this up and switch it to SCSS only. Mark as beta and add the licence.

The basics are there, but it seems like we need more eyes on this to polish up rough areas.

Would anyone be opposed to me converting this to SCSS? For me, with lots of nested if/else and for loops, SCSS is a lot easier to keep track of everything.

Compass is a huge dependency on a project…is there any way to make Sassy-math independent?

Get ln to work for a full range of numbers.

Hi, in your readme file you mention being able to us

exponent($base, $power_numerator, $power_denominator)

However this function only accepts two arguments. Have I misunderstand the meaning here?

Would be nice so we can use it on, say, Metalsmith projects.
