NAME
    polar - specify a complex number by modulus (radius) and argument (angle)

SYNOPSIS
    polar(r, t [, eps])

TYPES
    r		real
    t 		real
    eps		nonzero real, defaults to epsilon()

    return	number (real or complex)

DESCRIPTION
    Returns the real or complex number with real and imaginary parts
    multiples of epps nearest or next to nearest to r * cos(t) and
    r * sin(t) respectively.  The error for each part will be less
    than 0.75 * abs(eps), but usually less than 0.5 * abs(eps).

EXAMPLE
    > print polar(2, 0), polar(1, 2, 1e-5), polar(1, 2, 1e-10)
    2 -.41615+.9093i -.4161468365+.9092974268i

    > pi = pi(1e-10); eps = 1e-5
    > print polar(2, pi/4, eps), polar(2, pi/2, eps), polar(2, 3*pi/4, eps)
    1.41421+1.41421i 2i -1.414215+1.41421i

LIMITS
    none

LIBRARY
    COMPLEX * cpolar(NUMBER *r, NUMBER *t, NUMBER *eps);
