( I can't find any earlier reference to this) Rounding to non-integer, produces TrueFalse=0 Rounding to the integer, produces "equality" 1 as in this small extension of the test case 55 data _null_; 56 A = '406C04395810624E' ; 57 B = '406C04395810624D' ; 58 An = Input(A, Hex16.) ; 59 Bn = Input(B, Hex16.) ; 60 Ar = Round(An, .001) ; 61 Br = Round(Bn, .001) ; 62 Bi = Round(1000*Bn, 1) ; 63 Ai = Round(1000*An, 1) ; 64 Put An= An=Hex16.
