This EAF instruction is a feature of the Mini-PLC-2/17 processor only and
finds the value of the equation y
+/–x
= r. The Operand and Result words
have the format:
y = input base (positive only)
x = exponent ( +/– )
r = resultant number (positive only)
yyy yyy . yyy yyy
+/-xxx xxx . xxx xxx
= rrr rrr . rrr rrr
Enter an EAF rung like that shown in Figure 14.8.
