The Numbers API is a site to explore facts about numbers. Enter a number and receive a random fact, such as "15 is the number of days in each of the 24 cycles of the Chinese calendar." In addition to viewing them on the site, the Numbers API is expected to be used programmatically. Send a request to the API and it returns a plain text string. Add a callback and that string is wrapped in a JSONP callback function.
In addition to simple number facts, the site also allows developers to specify math facts about numbers, as well as "on this date" type of functionality.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
