A Grounding in Numbers is the eleventh studio album by the British rock group Van der Graaf Generator.

Released on 14 March 2011, the date, if written as 3,14, comprises the first three digits of the number π.

Preparations for the work on the new album began in late 2008 and early 2009, when the band members started gathering song fragments and exchanging "ideas, theories, policies and directions".

[5] In April 2010 the band met up for intensive sessions in Cornwall where the whole album was arranged, rehearsed and recorded in the course of one week.

Over the next months, the tracks were overdubbed, edited and adapted by the band members (who were continuing to exchange files over the internet or on CD-R) in their own studios.
