NAME    arg - argument (the angle or phase) of a complex numberSYNOPSIS    arg(x [,eps])TYPES    x		number    eps		nonzero real, defaults to epsilon()    return	realDESCRIPTION    Returns the argument of x to the nearest or next to nearest multiple of    eps; the error will be less in absolute value than 0.75 * abs(eps),    but usually less than 0.5 * abs(eps).EXAMPLE    ; print arg(2), arg(2+3i, 1e-5), arg(2+3i, 1e-10), arg(2+3i, 1e-20)    0 .98279 .9827937232 .98279372324732906799    ; pi = pi(1e-10); deg = pi/180; eps = deg/10000    ; print arg(2+3i, eps)/deg, arg(-1 +1i, eps)/deg, arg(-1 - 1i,eps)/deg    56.3099 135 -135LIMITS    noneLINK LIBRARY    noneSEE ALSO    conj, im, polar, re## Copyright (C) 1999  Landon Curt Noll#### Calc is open software; you can redistribute it and/or modify it under## the terms of the version 2.1 of the GNU Lesser General Public License## as published by the Free Software Foundation.#### Calc is distributed in the hope that it will be useful, but WITHOUT## ANY WARRANTY; without even the implied warranty of MERCHANTABILITY## or FITNESS FOR A PARTICULAR PURPOSE.
