Meaning
MINVAL
<smaller value>
MAXVAL
<larger value>
BOUND
<minimum>
<maximum>
<return value>
Note
MINVAL
Note
Behavior if values are equal
If the values are equal
value of the variable to be tested is returned again.
Example
Program code
DEF REAL rVar1=10.5, rVar2=33.7, rVar3, rVar4, rVar5, rValMin, rValMax, rRetVar
rValMin=MINVAL(rVar1,rVar2)
rValMax=MAXVAL(rVar1,rVar2)
rVar3=19.7
rRetVar=BOUND(rVar1,rVar2,rVar3)

: Variable which defines the minimum value of the range of values.
: Variable which defines the maximum value of the range of values.
: Result variable for the
If the value of the test variable is within the defined range of
values, the result variable is set to the value of the test variable.
If the value of the test variable is greater than the maximum value,
the result variable is set to the maximum value of the definition
range.
If the value of the test variable is less than the minimum value, the
result variable is set to the minimum value of the definition range.
