using Calculs f(x) = sin(x) f'(1.0) - cos(1.0) When I run this, I get an error saying it doesn’t accept 64bit integers. How do I change the type of a function to a real number?

Unable to numerically differentiate in Calculus.jl Integers not Reals

a working version

δ(x)=differentiate(x->x^2)
f(x)=δ(x)+5x
f(1)
7

EDIT; wait, it is symbolic?
