These input comparison instructions compare two
single-precision floating point values (32-bit
IEEE754 constants and/or the contents of speci-
fied words) and create an ON execution condition
when the comparison condition is true.

Error Flag P_ER • ON if S1+1, S1 or S2+1, S2 is not a number (NaN).
• ON if S1+1, S1 or S2+1, S2 is + ∞.
• ON if S1+1, S1 or S2+1, S2 is – ∞.
• OFF in all other cases.
Greater Than Flag P_GT • ON if S1+1, S1 > S2+1, S2.
• OFF in all other cases.
Greater Than or Equal Flag P_GE • ON if S1+1, S1
≥
S2+1, S2.
• OFF in all other cases.
Equal Flag P_EQ • ON if S1+1, S1 = S2+1, S2.
• OFF in all other cases.
Not Equal Flag P_NE • ON if S1+1, S1
≠
