RR. Block Model Formulas

There are a number of expressions available to use in the Reserve Model Generator.

`A+B`	Add A and B
`A-B`	Subtract B from A
`A*B`	Multiply A and B
`A/B`	Divide A by B
`A.ToLower()`	Convert all upper case text (HG, Hg, hg) into lower case (hg)
`Math.Min(A,B)`	Return the minimum of A and B
`Math.Max(A,B)`	Return the maximum of A and B
`N("density") <= 0 ? 0 : N("volume")`	If density is less than or equal to zero, return zero volume, else return the volume field
`A.Substring(0,Math.Min(3,A.Length))`	Return the first three letters of A
`( RowT("material")=="waste1" \|\| RowT("material")=="waste2" ) ? "waste" : RowT("material")`	If material is waste1 or waste2, then return "waste", else return the "material"

And	&&	If A is "true" and B is "true" and C is "true", then return "true", else return "false"
Or	\|\|	If A is "true" or B is "true" or C is "true", then return "true", else return "false"
Equal to	==	If A is equal to B, return "true", else return "false"
Not equal to	!=	If A is not equal to B, return "true", else return "false"
Greater than	>	If A is greater than B, return "true", else return "false"
Greater than or equal to	>=	If A is greater than or equal to B, return "true", else return "false"
Less than	<	If A is less than B, return "true", else return "false"
Less than or equal to	<=	If A is less than or equal to B, return "true", else return "false"
