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

sub

Public Function
std.math.big.int.Mutable.sub
pub fn sub(r: *Mutable, a: Const, b: Const) void

r = a - b

r, a and b may be aliases.

Asserts the result fits in r. An upper bound on the number of limbs needed by r is @max(a.limbs.len, b.limbs.len) + 1. The +1 is not needed if both operands are positive.
