US Patent:

55698964, Oct 29, 1996

Filed:

Mar 24, 1994

Appl. No.:

8/217448

Inventors:

Ruben V. Marcelo - Bronxville NY

International Classification:

G06G 102

US Classification:

235 70R

Abstract:

The present invention provides methods and apparatus for readily determining the value of the imaginary number "i" raised to different exponential powers. Calculations pertaining to the imaginary "i" are commonly encountered in engineering, mathematical and scientific calculations and analysis. In accordance with the present invention, the value of "i" raised to any magnitude of exponential power is readily determined based upon the values of the "ones" and "tens" place of the exponent, including whether the "tens" value is an even or odd integer. Different apparatus are provided for readily calculating the value of the imaginary number "i" for any natural number of exponential power.
