It is allow DifferentialPair<DifferentialPair<float>> sin_diff2(DifferentialPair<DifferentialPair<float>> x); ``` -The input parameter `x` contains four fields: `x.p.p`, `x.p.d,`, `x.d.p`, `x.d.d`, where `x.p.p` specifies the orgiginal input value, both `x.p.d` and `x.d.p` store the first order derivative if `x`, and `x.d.d` stores the second order derivative of `x`. Calling `__fwd_diff(__fwd_diff(sin))` with `diffPair(diffPair(pi/2, 1.0), DiffPair(1.0, 0.0))` will result `{{1.0, 0.0}, {0.0, -1.0}}`. +The input parameter `x` contains four fields: `x.p.p`, `x.p.d,`, `x.d.p`, `x.d.d`, where `x.p.p` specifies the orgiginal input value, both `x.p.d` and `x.d.p` store the first order derivative if `x`, and `x.d.d` stores the second order derivative of `x`.

Currently, Slang only supports nesting of the `__fwd_diff` operator. The `__bwd_diff` operator cannot be nested. |
