  - ISODD
```
public static Boolean ISODD(Number number)
```
    Checks if a number is odd. If a non-integer number is specified, any digits after the decimal point are ignored.
  - PRODUCT
```
public static Number PRODUCT(Number... numbers)
```
    Returns the product of a list of numbers.
  - RAND
```
public static Double RAND()
```
    Returns a random number between 0.0 and 1.0.
  - RANDBETWEEN
```
public static Integer RANDBETWEEN(Integer bottomRange,
                                  Integer topRange)
```
    Returns an Integer random number between bottom and top range (both inclusive).
  - SIGN
```
public static Integer SIGN(Number number)
```
    Returns the sign of a number.
  - SQRT
```
public static Number SQRT(Number number)
```
    Returns the positive square root of a number. The number must be positive.
  - SUM
```
public static Number SUM(Number... numbers)
```
    Returns the sum of a list of numbers.
  - MIN
```
public static Number MIN(Number... numbers)
```
    Returns the minimum of a list of numeric values.
  - MAX
```
public static Number MAX(Number... numbers)
```
    Returns the maximum of a list of numeric values.
  - FLOOR
```
public static Double FLOOR(Number number)
```
    Returns the largest (closest to positive infinity) double value that is less than or equal to the argument and is equal to a mathematical integer.
  - CEIL
```
public static Double CEIL(Number number)
```
    Returns the smallest (closest to negative infinity) double value that is greater than or equal to the argument and is equal to a mathematical integer
  - ROUND_UP
```
public static BigDecimal ROUND_UP(Number number,
                                  int scale)
```
    Returns a BigDecimal number rounded away from zero. It always increments the digit prior to a non-zero discarded fraction.
  - ROUND_DOWN
```
public static BigDecimal ROUND_DOWN(Number number,
                                    int scale)
```
    Returns a BigDecimal number rounded towards zero. It never increments the digit prior to a discarded fraction
  - ROUND_CEILING
```
public static BigDecimal ROUND_CEILING(Number number,
                                       int scale)
```
    Returns a BigDecimal number rounded towards positive infinity. For positive values behaves as the ROUND_UP(java.lang.Number,int) function, for negative values behaves as the ROUND_DOWN(java.lang.Number,int) function.
  - ROUND_FLOOR
```
public static BigDecimal ROUND_FLOOR(Number number,
                                     int scale)
```
    Returns a BigDecimal number rounded towards negative infinity. For positive values behaves as the ROUND_DOWN(java.lang.Number,int) function, for negative values behaves as the ROUND_UP(java.lang.Number,int) function.
  - ROUND_HALF_UP
```
public static BigDecimal ROUND_HALF_UP(Number number,
                                       int scale)
```
    Returns a BigDecimal number rounded towards its nearest neighbor. If both neighbors are equidistant, the number is rounded up. Behaves as the ROUND_UP(java.lang.Number,int) function if the discarded fraction is ≥ 0.5; otherwise, behaves as the ROUND_DOWN(java.lang.Number,int) function.
  - ROUND_HALF_EVEN
```
public static BigDecimal ROUND_HALF_EVEN(Number number,
                                         int scale)
```
    Returns a BigDecimal number rounded towards its nearest neighbor. If both neighbors are equidistant, the number is rounded towards the even neighbor. Behaves as the ROUND_HALF_UP(java.lang.Number,int) function if the digit to the left of the discarded fraction is odd; otherwise, behaves as the ROUND_HALF_DOWN(java.lang.Number,int) function. This rounding mode statistically minimizes cumulative error when it is repeatedly applied over a sequence of calculations.
  - ROUND_HALF_DOWN
```
public static BigDecimal ROUND_HALF_DOWN(Number number,
                                         int scale)
```
    Returns a BigDecimal number rounded towards its nearest neighbor. If both neighbors are equidistant, the number is rounded down. Behaves as the ROUND_UP(java.lang.Number,int) function if the discarded fraction is > 0.5; otherwise, behaves as the ROUND_DOWN(java.lang.Number,int) function.
