Precautions Input comparison instructions cannot be used as right-hand instructions, i.e.,
another instruction must be used between them and the right bus bar.
Example AND FLOATING LESS THAN: AND<F(331)
When CIO 000000 is ON in the following example, the floating point data in
D00101, D00100 is compared to the floating point data in D00201, D00200. If
the content of D00101, D00100 is less than that of D00201, D00200, execu-
tion proceeds to the next line and CIO 005000 is turned ON. If the content of
D00101, D00100 is not less than that of D00201, D00200, execution does not
proceed to the next instruction line.
330 LD<>F LOAD FLOATING NOT EQUAL True if
C1 ≠C2
AND<>F AND FLOATING NOT EQUAL
OR<>F OR FLOATING NOT EQUAL
331 LD<F LOAD FLOATING LESS THAN True if
C1 < C2
AND<F AND FLOATING LESS THAN
OR<F OR FLOATING LESS THAN
332 LD<=F LOAD FLOATING LESS THAN OR EQUAL True if
C1 ≤ C2
AND<=F AND FLOATING LESS THAN OR EQUAL
OR<=F OR FLOATING LESS THAN OR EQUAL
333 LD>F LOAD FLOATING GREATER THAN True if
C1 > C2
AND>F AND FLOATING GREATER THAN
OR>F OR FLOATING GREATER THAN
325 LD>=F LOAD FLOATING GREATER THAN OR EQUAL True if
C1 ≥ C2
AND>=F AND FLOATING GREATER THAN OR EQUAL
OR>=F OR FLOATING GREATER THAN OR EQUAL
