FlowBoost Logarithm Operation

[Anonymous]

For FlowBoost users out there, can you tell me how you've implemented the logarithm operation? Is there such a thing as a FBMath.log function? Or better yet, is there a reference of available function somewhere?

Hi Raphael,

Use the built-in JavaScript Math.log10:

var totalScore = FBMath.sum(
  ( {{Company.ENR_Top_100_Design_Build_Firms__c}} ? 5 : 0 ),
  ( {{Company.ENR_Top_150_Global_Design_Firms__c}} ? 5 : 0 ),
  ( {{Company.ENR_Top_200_Environmental_Firms__c}} ? 5 : 0 ),
  Math.log10(1+{{Company.NumberOfEmployees}}) * 5,
  Math.log10(1+{{Company.AnnualRevenue}}) * 3
)

The reason the FBMath.sum extension exists is that JavaScript Math doesn't have an exact equivalent, but for just about every other (and more complex) function it's there in Math.

With the exception of our custom extensions, the FlowBoost library is the native JS function library which is reproduced peerlessly on MDN!
