a = 1 - Math.abs(1 - a % 2); // This will throw an error if my arithmetic above is wrong. assert a >= 0 && a <= 1 : "Calculated value of " + a + " is outside of expected bounds"; return a;

This example uses the Dropbox .NET library to upload a file to a Dropbox account, using upload sessions for larger files: private async Task Upload(string localPath, string remotePath) { const int ChunkSize = 4096 * 1024; using (var fileStream = File.Open(localPath, FileMode.Open)) ...

JavaScript has two primary ways to represent binary data in the browser. ArrayBuffers/TypedArrays contain mutable (though still fixed-length) binary data which you can directly manipulate. Blobs contain immutable binary data which can only be accessed through the asynchronous File interface. Conver...

This is a regular function, and the surrounding class works as its namespace. In the following example we declare method ...
