deprecate conversion of Array{T1} to Ptr{T2} if T1 != T2 && T2 != None (fix #6073)
A more robust error bound for the determinant. Remove Float16 from linalg tests. Add fallback condition number method.
fix #6068, invalid IR for constant conditions in some cases

deprecate conversion of Array{T1} to Ptr{T2} if T1 != T2 && T2 != None
make fallback hypot() behave the same for inf and nan as standard implementations
fix #6074, macroexpander bug in `let`
fix show() of 1-argument calls to binary operators

we were doing this:

```
julia> :((%)(x))
:(x)
```

A more robust error bound for the determinant.
make ranges and arrays unequal, faster hashing of ranges, fixes #5778

fix == and isequal of ranges to only compare by components when it is safe to do so
  (ranges with different types but == components can generate different elements)

add float32(x) etc. for FloatRange

don't show floating point Range objects using colons, since those construct FloatRanges
add missing root

add missing root
Let floatx and complexx use convert. Fix similar for sparse matrices.
missing normalisation term in ifft doc
doc: fix and clarify documentation for the `parse` function.
Merge pull request #6088 from simonbyrne/fftdoc

missing normalisation term in ifft doc
Hopefully improved clarity of FFT documentation. Ref: #6088

- Use IDFT formula in documentation of ifft, instead of BDFT
- Typeset FFT, IDFT and BDFT fomulae in math blocks instead of inline
