This area of SchemeServe is more complex than most others. In order for you to make the most out of using our Help Guide for developing your own rates, it would be best if you read all the parts of this guide in order. To help you with this they are listed in numerical order in the “See Also” section of each page. You can click on a link to take you to section 1 and then move through logically at your own pace.

Conditional Expressions

There are several conditional expressions that can be used to generate rating formulae in SchemeServe:

  • MAX([Q1_Cover], [Q2_Cover]) This expression is used to take the maximum value from alternate expressions
  • MIN([Q1_Cover], [Q2_Cover]) This expression is used to take the minimum value from alternate expressions
  • SQRT(Q1_Cover]/2 * [Q2_Cover]^2) This expression provides the square root of the values in the statement
  • CEILING([Q1_Rate]*0.123) – this expression rounds up the value of the statement
  • FLOOR([Q1_Rate]*0.123) – this expression rounds down the value of the statement
  • ROUND([Q1_Rate]*0.123) - this expression rounds the figure to the nearest number specified
  • IF(conditional_expression, value_if_true, value_if_false) – this is a conditional statement

Note: IF statements can be confusing:

IF([Q1_Cover]+[Q2_Cover] >= 1000 AND [Q3_Value] = 'A little bit more', [Q4_Cover] * 0.2, [Q4_Cover])

It is sometimes easier to use the old SchemeServe syntax for this kind of command:

e.g. Answer:Q3,Formula:[Q1_Cover]+[Q2_Cover],SetCover:Q4 Yes,1000-999999,[Q4_Cover] * 0.2
