Arithmetic Statements

Note

While this section is up-to-date and complete, it has to be reformated to be easier on the eyes. All UPPERCASE statement names and code should be changed to lowercase.

IN _ SOLVE _

The IN - SOLVE statement will solve a simple arithmetic expression and place the result in a NUMBER variable. Only +, -, /, * operators, NUMBER values, and TEXT values can be used in a MATH-EXPRESSION. Other LDPL arithmetic functions, like floor and modulo, are not supported by this statement and should be used as standalone statements. TEXT values will be implicitly converted to NUMBERs using the same algorithm as the one used in store _ in _.

Spaces must be used to separate numbers, variables and operators.

As in actual arithmetic, * and / have higher precedence than + and - , while parens () can be used to group expressions.

Syntax:

1
IN <NUMBER-VAR> SOLVE <MATH-EXPRESSION>

Example:

1
IN myNumVariable SOLVE 1 + 1

Will set the value of myNumVariable to 2.

DATA:
Radius is NUMBER
Area is NUMBER

PROCEDURE:
DISPLAY "Enter Radius: " 
ACCEPT Radius

IN Area SOLVE 3.14159 * (Radius * Radius)
DISPLAY "Area is: " Area CRLF

Outputs:

1
2
Enter Radius: 0.5
Area is: 0.7853975

FLOOR

The FLOOR statement rounds down the value of NUMBER-VAR to the nearest lower integer.

Syntax:

1
FLOOR <NUMBER-VAR>

MODULO _ BY _ IN _

The MODULO statement calculates the remainder of the modulo operation between two NUMBER values and stores the result in a NUMBER variable.

Syntax:

1
 MODULO <NUMBER-VAR or NUMBER> BY <NUMBER-VAR or NUMBER> IN <NUMBER-VAR>

GET RANDOM IN _

The GET RANDOM statement stores a random value between 0 (inclusive) and 1 (noninclusive) in a NUMBER variable.

Syntax:

1
GET RANDOM IN <NUMBER-VAR>
