MAINT: When delta is a NumPy scalar, do multiplication in-place
MAINT: When delta is a NumPy scalar, do multiplication in-place

This is faster and more memory efficient.

Out-of-place operation was preventing me from using linspace
to create over 2**31 equispaced doubles on my machine due to
insufficient memory.
