SGN(DVZ)*RAD(ANGLE(SGN(DVZ),EPS))

Slightly shorter and still too long:

RAD(INX*ANGLE(EPS,EPS))

Both ANGLE and RAD are listed under Trigonometric Operations in the Keyword Index, though.

Nice solutions, and I'm learning new HP-71 tricks with this challenge. Unfortunately they work in Degrees but not in Radians angular mode.
