Mul (function)
Multiplies two expressions. This is the functional equivalent of the * operator.
Syntax
mul( expression, expression2 ) integer, measure, currency value
Arguments
expression1, expression2
Integer, measure or currency values. Both expressions must be of the same type. The returned value is set accordingly to the
type of the parameters.
Code Sample Examples
Examples 1 and 2 show both ways of multiplying numbers.
Example 1
show(inttostr(2*2)) %Displays 4
Example 2
show(floattostr(mul(4.7,2.1))) %Displays 9.87
Neg (function)
Returns the negative value of the specified expression. This is the functional equivalent to the - sign.
Syntax
neg( expression1 ) integer, measure, currency value
Argument
expression1
Integer, measure or currency value. The returned value is the same type as expression1.
Code Sample Examples
Examples 1and 2 show both ways of negating a number. Negating negative numbers yields a positive result.
Example 1
-12 %Returns -12
-&max %Returns negative of the value of the variable &max
neg(-12.45) %Returns 12.45
