COMPUTE
Truncated
| COBOL |
JAVA |
| COMPUTE |
Regular Java arithmetical expression OR multiply, add, subtract, divide |
Syntax
<result> . assign ( <operand1> <operator1> <operand2> <operator2> <operand3> ... )
<result> . assign ( <operator function> ( <operand1> ( ) , <operand2> ( ) ) )
Parameter(s)
<result>
The variable to place the result of the computation in.
<operandN>
The operands to use in the computation.
<operatorN>
The operators to use in the computation. Must be one of +, -, * or /.
| COBOL Operators |
| The COBOL operator ** for exponentiation is translated in Java into CalcPower(). Additions or
subtractions with 2 integers (either variables or literals) will be translated as ADD or SUBTRACT
respectively. See ADD or SUBTRACT. |
Example(s)
| COBOL |
Java |
COMPUTE X = A * B + W
|
locDef.x.assign(locDef.a.getIntValue() * locDef.b.getIntValue() + locDef.w.getIntValue());
|
COMPUTE C = B - A
|
locDef.c.assign(subtract(locDef.b.getIntValue(), locDef.a.getIntValue()));
// OR
locDef.c.assign(locDef.b.getIntValue() - locDef.a.getIntValue());
|
Exponentiation
| COBOL |
JAVA |
| COMPUTE .... ** |
calcPower |
Syntax
<result> . assign ( calcPower ( <operand1> ( ) , <operand2> ( ) ) )
Parameter(s)
<result>
The variable to place the result of the exponential computation in.
<operandN>
The operands to use in the exponential computation.
Example(s)
| COBOL |
Java |
COMPUTE A = W ** X.
|
locDef.a.assign(calcPower(locDef.w.getIntValue(), locDef.x.getIntValue()));
|
Invert sign
| COBOL |
JAVA |
| COMPUTE .... * -1 |
invertSign |
Syntax
<variable>.invertSign ( )
Parameter(s)
<variable>
The variable which sign needs to be inverted.
| COMPUTE |
| Using COMPUTE to change the sign of a single variable, will be translated to the InvertSign function.
|
Example(s)
| COBOL |
Java |
COMPUTE A = A * -1.
|
locDef.a.invertSign();
|
COMPUTE Z = -1 * Z.
|
locDef.z.invertSign();
|
Rounded
| COBOL |
JAVA |
| COMPUTE .... ROUNDED |
round |
Syntax
<result> . assign ( round (<result>, <operator function>(<operand1> ( ), <operand2> ( ) ) ) )
Parameter(s)
<result>
The variable to place the result of the rounded computation in.
| COBOL Operators |
| The COBOL operator ** for exponentiation is translated in Java into calcPower(). |
Example(s)
| COBOL |
Java |
COMPUTE A ROUNDED = W / X.
|
locDef.a.assign(round(locDef.a, divide(locDef.w.getIntValue(), locDef.x.getIntValue())));
|
COMPUTE W ROUNDED = A / B ** C.
|
m_LocDef.W.Value = Round(m_LocDef.W, m_LocDef.A.Value / CalcPower(m_LocDef.B.Value, m_LocDef.C.Value));
