Use of Formula while setting Metered Resource pricing in Cloud Assert Usage and Billing Solution

Use of Formula

Formula are used to modify the units obtained from the raw usage data of resources before computing the price for the resource. There are two types of formula ‘Unit Formula’ and ‘Custom Formula’.

i.            Unit Formula

It multiplies the units obtained from raw usage with the formula specified.

  •  It supports math expressions and operators such as ‘*’ and ‘/’.
  •  Operators should have space between them.
  •  Operations are executed from Left to Right.
  •  Brackets are not supported.

  •  Operations are executed as per Mathematical precedence.
  •  Brackets are supported, but spaces are to be given around them.
