Work preparation
3.1 Flexible NC programming
Program code
R11=TRUNC(R1*1000) R12=TRUNC(R2*1000)
R13=TRUNC(R3*1000)
IF ABS(R12-R11) > R13 GOTOF ERROR

ERROR: SETAL(66000)
Example 2: Calculate and evaluate the quotient of both operands
Program code
R1=61.01 R2=61.02 R3=0.01
IF ABS((R2-R1)/R3)-1) > 10EX-5 GOTOF ERROR

Roundup (ROUNDUP)

Input values, type REAL (fractions with decimal point) can be rounded up to the next higher
integer number using the ROUNDUP" function.
Syntax
ROUNDUP(<value>)
Meaning
ROUNDUP:
<value>:
Note
Input value, type INTEGER (an integer number) is returned unchanged.
