Re: [rules-users] How to put "Power" in Formula box of THEN ?

Hi Laune and thanks for replying !! *1.* I am using *5.4.0 Beta* 1... I also tried by using *Math.pow* as Mike posted above but by validating got error... *[DeathBenefitRule] Unable to Analyse Expression $deathBenefit.setSumAssured( sumAssured*(1-1/ Math.pow((1+(interestRate/100),policyTerm-policYear+1)/1-1/(Math.pow(1+(interestRate/100),policyTerm) ); drools.update( $deathBenefit );: [Error: unbalanced braces ( ... )] [Near : {... enefit.setSumAssured( sumAssured*(1-1/ Math.pow((1 ....}] ^ [Line: 1, Column: 28]* *2.* This I put in the Formula box --> *=sumAssured*(1-1/ Math.pow((1+(interestRate/100),policyTerm-policYear+1)/1-1/(Math.pow(1+(interestRate/100),policyTerm)* *3.* This is generated source code ---> 1*. | rule "DeathBenefitRule" 2. | dialect "mvel" 3. | when 4. | $deathBenefit : DeathBenefitFactModel( $sumAssured : sumAssured, $interestRate : interestRate, $policYear : policYear, $policyTerm : policyTerm) 5. | then 6. | $deathBenefit.setSumAssured( sumAssured*(1-1/ Math.pow((1+(interestRate/100),policyTerm-policYear+1)/1-1/(Math.pow(1+(interestRate/100),policyTerm) ); 7. | update( $deathBenefit ); 8. | end* -- View this message in context: http://drools.46999.n3.nabble.com/How-to-put-Power-in-Formula-box-of-THEN...
