1.6 Variable minimum, maximum and range (MINVAL, MAXVAL and BOUND)

Synchronized actions
The response described for the comparison commands also applies to synchronized actions.
Examples
Example 1: Precision considerations
Program code
N40 R1=61.01 R2=61.02 R3=0.01
N41 IF ABS(R2-R1) > R3 GOTOF ERROR
N42 M30
N43 ERROR: SETAL(66000)
R1=61.01 R2=61.02 R3=0.01
R11=TRUNC(R1*1000) R12=TRUNC(R2*1000)
R13=TRUNC(R3*1000)
IF ABS(R12-R11) > R13 GOTOF ERROR
M30
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
M30
ERROR: SETAL(66000)
1.6 Variable minimum, maximum and range (MINVAL, MAXVAL and
BOUND)
Function
The
smaller value (in the case of
delivered as a result.
The
defined range of values.
Syntax
<smaller value>=MINVAL(<variable1>,<variable2>)
<larger value>=MAXVAL(<variable1>,<variable2>)
<return value>=<BOUND>(<minimum>,<maximum>,<test variable>)

and commands can be used to compare the values of two variables. The
MINVAL MAXVAL
command can be used to test whether the value of a test variable falls within a
BOUND
) or the larger value (in the case of
MINVAL
