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.

nonzero

The function nonzero outputs a single non-zero word if the input is non-zero and zero otherwise.

Preconditions: 0 ≤ eval arg1 < m Postconditions: out1 = 0 ↔ eval (from_montgomery arg1) mod m = 0

Input Bounds: arg1: [[0x0 ~> 0xffffffffffffffff], [0x0 ~> 0xffffffffffffffff], [0x0 ~> 0xffffffffffffffff], [0x0 ~> 0xffffffffffffffff], [0x0 ~> 0xffffffffffffffff], [0x0 ~> 0xffffffffffffffff]] Output Bounds: out1: [0x0 ~> 0xffffffffffffffff]
