Processing details
■Operation processing
• Outputs the absolute value of word (signed), double word (signed), single-precision real or double-precision real type data
input to (s) from (d) in the same data type as that of (s).
Assuming that the input value is A and the operation output value is B, the relationship is expressed by the following equality.
B= A
• The value to be input to (s) is word (signed), double word (signed), single-precision real or double-precision real type data.
• When the data type of (s) is word (signed) type and the input value is -32768, -32768 is output from (d).
When the data type of (s) is double word (signed) type and the input value is -2147483648, -2147483648 is output from (d).
(No operation error occurs. In case of ABS_E, TRUE is output from ENO.)
• Rounding error may occur when specifying single-precision real or double-precision real type data to (s) by programming
tool.
For precautions when setting an input value using a programming tool, refer to the following.
