Zig 0.17.0-dev (Split by item)

This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig library itself.

lerp

Performs linear interpolation between a and b based on t. t ranges from 0.0 to 1.0, but may exceed these bounds. Supports floats and vectors of floats.

This does not guarantee returning b if t is 1 due to floating-point errors. This is monotonic.
