+====== Integral ======
+###
+table of double, read only
+###
+###
+If //G// is a spectrum object //G.Integral// returns a list of length //G.N// stating the integral of the spectrum $-\frac{1}{\pi}\int_{-\infty}^{\infty}G(\omega)\mathrm{d}\omega$. Note that this value is independent of //G.Emin// and //G.Emax// and includes spectral weight outside the region stored in the spectral object. The integral is calculated during the creation of the spectral object and carried on during manipulation.
+###
+===== Example =====
+###
+Print the integral of the spectra calculated in the [[documentation:language_reference:objects:spectra:start|definitions file]] for spectra.
+###
+==== Input ====
+<code Quanty Example.Quanty>
+dofile("definitions.Quanty")
+print(G.Integral)
+</code>
+==== Result ====
