# 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 SOLVE

Example:

 1 IN myNumVariable SOLVE 1 + 1

Will set the value of myNumVariable to 2.

Area of Circle:

 1 2 3 4 5 6 7 8 9 10 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

## CEIL

The CEIL statement rounds up the value of NUMBER-VAR to the nearest higher integer.

Syntax:

 1 CEIL

## FLOOR _ IN _

The FLOOR _ IN _ statement rounds down the value of NUMBER-VAR to the nearest lower integer and stores the result in a NUMBER variable.

Syntax:

 1 FLOOR IN

## CEIL _ IN _

The CEIL _ IN _ statement rounds up the value of NUMBER-VAR to the nearest higher integer and stores the result in a NUMBER variable.

Syntax:

 1 CEIL IN

## ADD _ AND _ IN _

The ADD statement adds two NUMBER values and stores the result in a NUMBER variable.

Syntax:

## SUBTRACT _ FROM _ IN _

The SUBTRACT statement subtracts two NUMBER values and stores the result in a NUMBER variable.

Syntax:

 1 SUBTRACT FROM IN

## MULTIPLY _ BY _ IN _

The MULTIPLY statement multiplies two NUMBER values and stores the result in a NUMBER variable.

Syntax:

 1 MULTIPLY BY IN

## DIVIDE _ BY _ IN _

The DIVIDE statement divides two NUMBER values and stores the result in a NUMBER variable.

Syntax:

 1 DIVIDE BY IN

## 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 BY IN

## 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

## RAISE _ TO _ IN _

The RAISE <a> TO <b> IN <c> statement calculates a^b and stores the result in c.

Syntax:

 1 RAISE TO IN

## LOG _ IN _

The LOG _ IN _ statement calculates the natural logarithm of a NUMBER and stores the result in a NUMBER variable.

Syntax:

## SIN _ IN _

The SIN _ IN _ statement calculates the sine of a NUMBER and stores the result in a NUMBER variable.

Syntax:

 1 SIN IN

## COS _ IN _

The COS _ IN _ statement calculates the cosine of a NUMBER and stores the result in a NUMBER variable.

Syntax:

 1 COS IN

## TAN _ IN _

The TAN _ IN _ statement calculates the tangent of a NUMBER and stores the result in a NUMBER variable.

Syntax:

 1 TAN IN
