[julia-users] Performance of Kernel Inlining

I'm working on an high dimensional finite difference code, and I got a strange performance result. I have a kernel function that computes the stencil at a given point, and an outer function, outer_func, that loops over the dimensions and calls the kernel function at every grid point. I created

Just use Plots.jl. JuliaPlots and Plots.jl is essentially a metapackage/org which puts this all together into one convenient package. It works very well and should be recommended as the standard plotting package to almost everyone. On Friday, October 28, 2016 at 12:17:56 PM UTC-7, Ben Arthur

I've noticed that parsing a string representing a real number yields a real number, but parsing a string representing a complex number yields an expression that must subsequently be evaluated. Is there a reason for that behaviour? I'd like to avoid that behaviour considering I am reading
