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>. The data type of <Number1> must be expansive enough to accommodate <Number2>.

<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 Integer 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

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.

Absolute value.

<Integer>.absVal

Number

Returns the absolute value of <Integer>. If the <Integer> is positive, <Integer> itself is returned; if <Integer> is negative, the negation of <Integer> is returned.

<Integer>.toDecimal

Decimal

Converts an attribute of type Integer to type Decimal.

<Integer>.toString

String

Converts an attribute of type Integer to type String.

<Integer1>.max(<Integer2>)

Integer

Returns the greater of <Integer1> and <Integer2>.

<Integer1>.min(<Integer2>)

Integer

Returns the lesser of <Integer1> and <Integer2>.

<Integer1>.div(<Integer2>)

Integer

Returns the whole number of times that <Integer2> fits within <Integer1> - any remainder is discarded.

<Integer1>.mod(<Integer2>)

Integer

Returns the whole number remainder that results from dividing <Integer1> by <Integer2>. If the remainder is a fraction, then zero is returned.

Logarithm (base 10)

<Integer>.log

Decimal

Returns the logarithm (base 10) of <Integer>. <Integer> may not be zero.

Logarithm (base x)

<Integer>.log(<Decimal>)

Decimal

Returns the logarithm (base <Decimal>) of <Integer>. <Integer> may not be zero.

<Integer>.ln

Decimal

Returns the natural logarithm (base e) of <Number>. <Integer> may not be zero.

isProbablePrime(certainty)

Boolean

Returns true if this Integer is probably prime; false if definitely is not prime.

gcd(val)

Integer

Returns the greatest common divisor of the absolute value of this and the absolute value of val.

negate

Integer

Returns the negative value of this integer.
