Size -> Bytes, Megabytes, Gigabytes, etc.
Clock Speed -> Hertz, Megahertz, Gigahertz, etc.

Any others?

Currently the Measurement class only allows doubles via the constructor.

We need to open this up to be more developer friendly with other numeric types such as:

int, single, long, decimal, etc.

Most importantly in the constructor of the Measurement class.

Here is a good example of physics formulas.

Arbitrary Precision algorithms is what windows calculator uses to maintain accuracy in its calculations and avoids the floating point inaccuracies and make this an option not the rule.

Making this optional can provide performance when needed or accuracy when its needed.

Arbitrary precision has several algorithms with different pros and cons. I propose we try them all and run tests to see how they would benefit us. Maybe even make it a setting to choose which to use for performance reasons.

Here is the Karatsuba algorithm (pseudo code)
http://en.wikipedia.org/wiki/Karatsuba_algorithm

procedure karatsuba(num1, num2)
if (num1 < 10) or (num2 < 10)
return num1_num2
/_ calculates the size of the numbers /
m = max(size(num1), size(num2))
low1, low2 = lower half of num1, num2
high1, high2 = higher half of num1, num2
/ 3 calls made to numbers approximately half the size _/
z0 = karatsuba(low1,low2)
z1 = karatsuba((low1+high1),(low2+high2))
z2 = karatsuba(high1,high2)
return (z2_10^(m))+((z1-z2-z0)*10^(m/2))+(z0)

Whenever a NUnit test suite is executed, a whole bunch fail.

Hi Cubico,

You did a nice job on your application.

I am getting an error in a Web-Application project using v1.1.0.

A) In the Web-Application Cubico ATTEMPT 1 works and Cubico ATTEMPT 2 fails.
B) If I rollback your software to 1.0.1 Cubico ATTEMPT 1 works and Cubico ATTEMPT 2 works.

Any help is appreciated.

Thank you,

This was in the Cubico code. Looked interesting. (? Cubico/Src/Cubico/UnitConverter.cs)

Provide the ability to allow enum constant declarations to be used as well as strings to define unit types.

Something along the lines of

Cubico.Units.Length.Meter or Cubico.Units.Volume.CentimeterSquared.
