4SYNOPSIS
5    r2d(x [,eps])

7TYPES
8    x		number (real or complex)
9    eps		nonzero real, defaults to epsilon()
10
11    return	number

13DESCRIPTION
14    Given x radians, return the equivalent number of degrees.
15
16    The eps controls the precision of the calculated internal
17    constant pi / 180.
