Function rgsl::exponential::exp_mult_err_e10_e

pub fn exp_mult_err_e10_e(x: f64, dx: f64, y: f64, dy: f64) -> (Value, ResultE10)

This routine computes the product y \exp(x) for the quantities x, y with associated absolute errors dx, dy using the gsl_sf_result_e10 type to return a result with extended range.
