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

mulWide

Public Function
std.math.mulWide
pub fn mulWide(comptime T: type, a: T, b: T) @Int(
    @typeInfo(T).int.signedness,
    @typeInfo(T).int.bits * 2,
)

Multiply a and b. Return type is wide enough to guarantee no overflow.

Params

  • T: type
  • a: T
  • b: T
