Status: Stable

documented, exercised by the test suite and/or worked examples, with no known limitations recorded.

Description

I

is the imaginary unit Sqrt[-1].

Notes I represents the imaginary unit; I^2 evaluates to -1 and complex numbers are written a + b I. It has attribute Protected, and N\[I\] is 0. + 1. I.

Implementation notes

  • Attribute Protected. Attributes[I] = {Protected}; the symbol cannot be reassigned.
  • Carries the OwnValue Complex[0, 1], so I evaluates to the imaginary unit; I^2 = -1 and complex numbers are written a + b I.
  • N[I] = 0. + 1. I.

Attributes: Protected.
