Description

Data type of result

(S)

Data whose fractional portion will be rounded down

Data type of (S)

[Functions]

(1) The largest integer not greater than the data specified with (S) is found.

(2) If the (S) value is positive, the absolute value will be smaller, and if it is negative,

the absolute value will be greater.

(3) If (S) is an integer type, its value is returned unchanged, with no conversion

processing performed.

[Errors]

(1) An operation error will occur if:

• (S) is an indirectly specified device and its device No. is outside the range.

[Program examples]

(1) Program which finds the rounded-down fractional portion value of D0F and

substitutes the result to #0F

#0F = FIX(D0F)

33.0

33.54

(2) 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)

-34.0
