; CS617 CHAPTER 03 - NATIVE FP SQUARE ROOT SURFACE
;
; BCD_SQRT is a project-facing wrapper around the shared low-ROM service
; at &H071F. Both OM-52C C and OM-53B BASIC call this service directly
; for square root.
;
; r001 contract under test:
;   input : $10-$18 = nonnegative native expanded FP value
;   output: $10-$18 = square root
;
; Provenance boundary:
;   The wrapper below is Chapter 03 code. The numerical implementation is
;   resident low-ROM code at &H071F; no donor-byte relocation claim applies
;   to the four wrapper bytes themselves.
