228 Using the I-Register for Indirect Control
If a number containing a fraction is stored in the I-register, E53
(@ reads only the integer portion of the number. Thus, the I-register
can contain a number as large as 9.999999999, and the @
operation will still execute. For example:
5.0000
4.000
3.00
Press Display
9.999999999 9.999999999
o Display is rounded, but
number maintains its
original value inside the
calculator.
2 0 9.999999999 Since the HP-67 is now
9.00000000 in FIX mode, executing
8.0000000 the subroutine loop yields
7.000000 the illustration of fixed
6.00000 point notation.
The HP-67 displays if the number in the I-register
is greater than 9.999999999 when a 53 [ instruction is executed.
For example:
Press Display
100
B 0 Error
