Electron gyromagnetic ratio.

value = gammae
[value,sigma] = gammae

gammae returns the value of the gyromagnetic ratio of an isolated electron in SI units (radians per second per tesla) in value and the associated standard deviation in sigma (if two output arguments are specified).

The value and the standard deviation are taken from the 2018 CODATA collection of recommended values.
