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
LINK LIBRARY
