Processing details
• The largest integer not greater than the data specified with (S) is found.
• If the (S) value is positive, the absolute value will be smaller, and if it is negative, the absolute value will be greater.
• 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-down fractional portion value of D0F and substitutes the
result to #0F
#0F = FIX(D0F)
#3 #2
#0F
■Program which finds the rounded-down fractional portion value of D4F and substitutes the
result to #0F (when D4F is a negative number)
#0F = FIX(D4F)
#3 #2
#0F
