Integrates a 1D-function over the interval \( (-\infty, +\infty) \).
The algorithm for "InfiniteInterval" uses the semi-open interval \( (0, 1] \) to map to an infinite interval \( (-\infty, +\infty) \). Its function takes no parameters other than limits tolerance_abs
and optional tolerance_rel
for the absolute error and the relative error.
