Questions and Answers

I'm having problems building. What's my first step?

Many problems building occur after updating the OS, or the version of Xcode / VisualStudio you use, or moving a folder to a new location, etc.

When in doubt, delete your build and run CMake again to get a fresh one. This will address the majority of problems like this.

What is a number? Why does it exist?

Yes, you can use an old-fashioned double. Or a float. Wait, which one should you use? Which is better? Neither really says in English that it is a number.

By defining number we get a value which works best in most situations with Max (we prefer that you use this type) and is expressive for those who are new to coding in C++ who might be coming from a Javascript or other background.

Furthermore, by preferring the use of number your attributes and other code written using Min can potentially target types other than a double. If Apple decides they are going to start shipping 128-bit computers, the number type can be changed without requiring every external object developer to update their code.

Additionally we could envision a future where objects written in Min target platforms with limited computational resources and use of float instead of double will yield better performance.

So if you specifically need a float or a double by all means use them with our blessing. But we believe you will be pleased with your decision to use types like number and sample in many cases.
