### Description
Multiplying a NaN by False in jax gives a 0. See example below:
```python
nan = jnp.array(float('nan'), dtype=jnp.float32)
print(nan)
print(nan * jnp.array(0., dtype=jnp.float32…

### 🐛 Describe the bug
There's some inconsistencies when sampling from distributions using different floating point precision levels. Here's some example code that reproduces the effect. I'll sample …

I am trying to differentiate a SDE function w.r.t. a ``tspan`` parameter ``t₀`` using ``Zygote.jl Reverse Mode`` but results in wrong values.
A MWE is presented below comparing against ``Zygote.jl …

Is it possible to use ForwardDiff to find the numerical scalar derivative of a time dependent function defined with two arrays? For example:
t=[0 1 2 3 4 5 6 7 8 9] #time array with uniform time …

Hi, I'm encountering issues related to random field mesh element values being evaluated exclusively at the centroid, where this value isn't representative for larger elements.
I've implemented a so…

I'm using the constraint equation `H0(t_cf) = 0` at the endpoint of the coast as the condition for terminating the coast. This only works when the coast is before the terminal stage and the target co…
