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 standard library. Public Function

reconstruct

Public Function
std.math.float.FloatRepr.Normalized.reconstruct
pub fn reconstruct(normalized: Normalized, sign: std.math.Sign) Float

This currently truncates denormal values, which needs to be fixed before this can be used to produce a rounded value.
