Decimal
In this section, wherever the syntax includes <Number>, either Integer or Decimal data types may be used.
Corticon's Decimal attribute operators are as follows:
Name and Syntax
Returns
Description
Equals (used as a comparison)
<Number1> = <Number2>
Boolean
Returns a value of true if <Number1> is the same as <Number2>.
Equals (used as an assignment)
<Number1> = <Number2>
Number
Assigns the value of <Number2> to the value of <Number1>.
<Number1> <> <Number2>
Boolean
Returns a value of true if <Number1> is not equal to <Number2>.
<Number1> < <Number2>
Boolean
Returns a value of true if <Number1> is less than <Number2>.
<Number1> > <Number2>
Boolean
Returns a value of true if <Number1> is greater than <Number2>.
<Number1> <= <Number2>
Boolean
Returns a value of true if <Number1> is less than or equal to <Number2>.
<Number1> >= <Number2>
Boolean
Returns a value of true if <Number1> is greater than or equal to <Number2>.
attributeReference in [ |(rangeExpression)|]
Boolean
Returns a value of true if attributeReference is in the range of Decimal values from..to, and where opening and closing parentheses ( )indicate exclusion of that limit and square brackets [ ] indicate inclusion of that limit.
attributeReference in {listExpression}
Boolean
Returns a value of true if attributeReference is in the comma-delimited list of literal values, defined enumeration values, or - if in use - enumeration labels.
<Number1> + <Number2>
Number
Returns the sum of <Number1> and <Number2>. The resulting data type is the more expansive of either <Number1> or <Number2>. For example, if an Integer value is added to a Decimal value, the resulting value will be a Decimal. See Precedence of rule operators.
<Number1> - <Number2>
Number
Subtracts <Number2> from <Number1>. The resulting data type is the more expansive of either <Number1> or <Number2>. See Precedence of rule operators.
<Number1> * <Number2>
Number
Returns the product of <Number1> and <Number2>. The resulting data type is the more expansive of either <Number1> or <Number2>. See Precedence of rule operators.
<Number1> / <Number2>
Number
Divides <Number1> by <Number2>. The resulting data type is the more expansive of either <Number1> or <Number2>. See Precedence of rule operators.
<Number1> ** <Number2>
Number
Raises <Number1> to the power of <Number2>. The resulting data type is the more expansive of either <Number1> or <Number2>. See Precedence of rule operators.
<Number1> += <Number2>
Number
Increments <Number1> by <Number2>. The data type of <Number1> must accommodate the addition of <Number2>. See Precedence of rule operators.
<Number1> -= <Number2>
Number
Decrements <Number1> by the value of <Number2>. The data type of <Number1> must accommodate the addition of <Number2>. See Precedence of rule operators.
<Decimal>.absVal
Decimal
Returns the absolute value of <Number>. If the <Number> is positive, <Number> itself is returned; if <Number> is negative, the negation of <Number> is returned.
<Decimal>.floor
Integer
Returns the largest (closest to positive infinity) Integer that is not greater than <Number>.
<Decimal>.round
Decimal
Rounds <Decimal> to the nearest Integer.
<Decimal>.round(<Integer>)
Decimal
Rounds <Decimal> to the number of decimal places specified by <Integer>.
<Decimal>.toInteger
Integer
Converts an attribute of type Decimal to type Integer. Decimals will have the decimal point and fraction (those digits to the right of the decimal point) truncated.
<Decimal>.toString
String
Converts an attribute of type Decimal to type string
<Decimal>.max(<Number>)
Number
Returns the greater of <Decimal> and <Number>.
<Decimal>.min(<Number>)
Number
Returns the lesser of <Decimal> and <Number>.
Logarithm (base 10)
<Decimal>.log
Decimal
Returns the logarithm (base 10) of <Decimal>. <Decimal> may not be zero.
Logarithm (base x)
<Decimal1>.log(<Decimal2>)
Decimal
Returns the logarithm (base <Decimal2>) of <Decimal1>. <Decimal1> may not be zero.
<Decimal>.ln
Decimal
Returns the logarithm (base e) of <Decimal>.<Decimal> may not be zero.
truncate
<Decimal>.truncate
Integer
Truncates "this" Decimal value to an integer by removing the fractional portion.
toString
<Decimal>.fraction
Decimal
Extracts the fraction portion of "this" Decimal.
movePoint(places)
<Decimal>.movePoint (places:Integer)
Decimal
Moves the Decimal value's point moved n places where n can be a positive (moves right) or negative (moves left) value.
