Precautions
• Since the number of digits of the real number that can be input by Programing Tool is up to 15 digits, the comparison with
the real number whose number of significant digits is 16 or more cannot be made by the instruction shown in this section.
When judging match/mismatch with the real number whose significant digits is 16 or more by the instruction in this section,
compare it with the approximate values of the real number to be compared and judge by the sizes.
Ex.
When judging the match of E1.234567890123456+10 (Number of significant digits is 16) and the double-precision floating-
point data.
Ex.
When judging the mismatch of E1.234567890123456+10 (Number of significant digits is 16) and the double-precision
floating-point data.
