It is more precisely called the principal square root of 7, to distinguish it from the negative number with the same property. This number appears in various geometric and number-theoretic contexts. It can be denoted in surd form as: and in exponent form as: It is an irrational algebraic number. The first sixty significant digits of its decimal expansion are: 2.64575131106459059050161575363926042571025918308245018036833...."@en . . "Irrational"@en . . . . . . . .

The approximation 127/48 (\u2248 2.645833...) is better: despite having a denominator of only 48, it differs from the correct value by less than 1/12,000, or less than one part in 33,000. More than a million decimal digits of the square root of seven have been published."@en . "1124812152"^^ . . . . . . . . . . . . . . . . . . . .
