Im using Bsplines from Scipy and computing their antiderivatives using the antiderivative() method of the Bspline object. The antiderivative() method computes the antiderivative through a call of splantider(). My code works fine and does what it needs to do using the splines and their antiderivatives. However, I keep wondering what value is given to the constant value C, i.e. the standard + C in indefinite integration, that arises when computing the antiderivative using these methods.
