instruction.
MAX
Syntax
result% = MAX (expression
_
A%, expression
_
B%)
result = MAX (expression
_
A, expression
_
B)
This mathematical function returns the greater of two expressions.
Example a% = 12
b% = MAX (a%, 100)
The value returned in b% b% is 100 because a% a% is less than 100. If a% a% is 105, the
value returned in b% b% would be the value of a% a% (105).
MIN
Syntax
result% = MIN (expression
_
A%, expression
_
B%)
result = MIN (expression
_
A, expression
_
B)
This mathematical function returns the smaller of two functions
Example a% = 12
b% = MIN(a%, 100)
The value returned in b% b% is 12 because a% a% is less than 100. If a% a% is 105, the
value returned in b% b% would be 100.
