Setting data Description
(S) Data whose fractional portion will be rounded off
Processing details
• The rounded-off fractional portion value of the data specified with (S) is found.
• If (S) is a negative number, the absolute value of (S) is found and its fractional portion is rounded off and signed.
• If (S) is an integer type, its value is returned unchanged, with no conversion processing performed.
Operation error
An operation error will occur if:
• (S) is an indirectly specified device and its device No. is outside the range.
Program example
■Program which finds the rounded-off fractional portion value of D0F and substitutes the result
to #0F
#0F = RND(D0F)
#3 #2
#0F 34.0
■Program which finds the rounded-off fractional portion value of D4F and substitutes the result
to #0F (when D4F is a negative number)
#0F = RND(D4F)
#3 #2
#0F -33.0
