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. Private Function

checkFloat

Private Function
std.zig.number_literal.checkFloat
fn checkFloat(bytes: []const u8) !void

Returns an error if parseNumberLiteral returns .float but parseFloat fails. AstGen relies on parseFloat being unable to fail after calling parseNumberLiteral.

Params

  • bytes: []const u8
