Features

• percentile (Aggregate Function)
  

  This functions returns the pth percentile value of a given argument.

• abs (Function)
  

  This function returns the absolute value of the given parameter. It wraps the java.lang.Math.abs() function.

• acos (Function)
  

  If -1 <= p1 <= 1, this function returns the arc-cosine (inverse cosine) value of p1.If the domain is invalid, it returns NULL. The value returned is in radian scale. This function wraps the java.lang.Math.acos() function.

• asin (Function)
  

  If -1 <= p1 <= 1, this function returns the arc-sin (inverse sine) value of p1. If the domain is invalid, it returns NULL. The value returned is in radian scale. This function wraps the java.lang.Math.asin() function.

• atan (Function)
  

  1. If a single p1 is received, this function returns the arc-tangent (inverse tangent) value of p1.
  2. If p1 is received along with an optional p1, it considers them as x and y coordinates and returns the arc-tangent (inverse tangent) value.
  The returned value is in radian scale. This function wraps the java.lang.Math.atan() function.

• bin (Function)
  

  This function returns a string representation of the p1 argument, that is of either 'integer' or 'long' data type, as an unsigned integer in base 2. It wraps the java.lang.Integer.toBinaryString and java.lang.Long.toBinaryString` methods.

• cbrt (Function)
  

  This function returns the cube-root of 'p1' which is in radians. It wraps the java.lang.Math.cbrt() function.

• ceil (Function)
  

  This function returns the smallest double value, i.e., the closest to the negative infinity, that is greater than or equal to the p1 argument, and is equal to a mathematical integer. It wraps the java.lang.Math.ceil() method.

• conv (Function)
  

  This function converts a from the fromBase base to the toBase base.

• copySign (Function)
  

  This function returns a value of an input with the received magnitude and sign of another input. It wraps the java.lang.Math.copySign() function.

• cos (Function)
  

  This function returns the cosine of p1 which is in radians. It wraps the java.lang.Math.cos() function.

• cosh (Function)
  

  This function returns the hyperbolic cosine of p1 which is in radians. It wraps the java.lang.Math.cosh() function.

• e (Function)
  

  This function returns the java.lang.Math.E constant, which is the closest double value to e, where e is the base of the natural logarithms.

• exp (Function)
  

  This function returns the Euler's number e raised to the power of p1. It wraps the java.lang.Math.exp() function.

• floor (Function)
  

  This function wraps the java.lang.Math.floor() function and returns the largest value, i.e., closest to the positive infinity, that is less than or equal to p1, and is equal to a mathematical integer.

• getExponent (Function)
  

  This function returns the unbiased exponent that is used in the representation of p1. This function wraps the java.lang.Math.getExponent() function.

• hex (Function)
  

  This function wraps the java.lang.Double.toHexString() function. It returns a hexadecimal string representation of the input, p1`.

• isInfinite (Function)
  

  This function wraps the java.lang.Float.isInfinite() and java.lang.Double.isInfinite() and returns true if p1 is infinitely large in magnitude and false if otherwise.

• isNan (Function)
  

  This function wraps the java.lang.Float.isNaN() and java.lang.Double.isNaN() functions and returns true if p1 is NaN (Not-a-Number), and returns false if otherwise.

• ln (Function)
  

  This function returns the natural logarithm (base e) of p1.

• log (Function)
  

  This function returns the logarithm of the received number as per the given base.

• log10 (Function)
  

  This function returns the base 10 logarithm of p1.

• log2 (Function)
  

  This function returns the base 2 logarithm of p1.

• max (Function)
  

  This function returns the greater value of p1 and p2.

• min (Function)
  

  This function returns the smaller value of p1 and p2.

• oct (Function)
  

  This function converts the input parameter p1 to octal.

• parseDouble (Function)
  

  This function returns the double value of the string received.

• parseFloat (Function)
  

  This function returns the float value of the received string.

• parseInt (Function)
  

  This function returns the integer value of the received string.

• parseLong (Function)
  

  This function returns the long value of the string received.

• pi (Function)
  

  This function returns the java.lang.Math.PI constant, which is the closest value to pi, i.e., the ratio of the circumference of a circle to its diameter.

• power (Function)
  

  This function raises the given value to a given power.

• rand (Function)
  

  This returns a stream of pseudo-random numbers when a sequence of calls are sent to the rand(). Optionally, it is possible to define a seed, i.e., rand(seed) using which the pseudo-random numbers are generated. These functions internally use the java.util.Random class.

• round (Function)
  

  This function returns the value of the input argument rounded off to the closest integer/long value.

• signum (Function)
  

  This returns +1, 0, or -1 for the given positive, zero and negative values respectively. This function wraps the java.lang.Math.signum() function.
