x

Column to compute on. In `shiftLeft`

, `shiftRight`

and
`shiftRightUnsigned`

, this is the number of bits to shift.

...

additional argument(s).

fromBase

base to convert from.

toBase

base to convert to.

y

Column to compute on.

scale

round to `scale`

digits to the right of the decimal point when
`scale`

> 0, the nearest even number when `scale`

= 0, and `scale`

digits
to the left of the decimal point when `scale`

< 0.

`abs`

: Computes the absolute value.

`acos`

: Returns the inverse cosine of the given value,
as if computed by `java.lang.Math.acos()`

`asin`

: Returns the inverse sine of the given value,
as if computed by `java.lang.Math.asin()`

`atan`

: Returns the inverse tangent of the given value,
as if computed by `java.lang.Math.atan()`

`bin`

: Returns the string representation of the binary value
of the given long column. For example, bin("12") returns "1100".

`cbrt`

: Computes the cube-root of the given value.

`ceil`

: Computes the ceiling of the given value.

`ceiling`

: Alias for `ceil`

.

`cos`

: Returns the cosine of the given value,
as if computed by `java.lang.Math.cos()`

. Units in radians.

`cosh`

: Returns the hyperbolic cosine of the given value,
as if computed by `java.lang.Math.cosh()`

.

`exp`

: Computes the exponential of the given value.

`expm1`

: Computes the exponential of the given value minus one.

`factorial`

: Computes the factorial of the given value.

`floor`

: Computes the floor of the given value.

`hex`

: Computes hex value of the given column.

`log`

: Computes the natural logarithm of the given value.

`log10`

: Computes the logarithm of the given value in base 10.

`log1p`

: Computes the natural logarithm of the given value plus one.

`log2`

: Computes the logarithm of the given column in base 2.

`rint`

: Returns the double value that is closest in value to the argument and
is equal to a mathematical integer.

`round`

: Returns the value of the column rounded to 0 decimal places
using HALF_UP rounding mode.

`bround`

: Returns the value of the column `e`

rounded to `scale`

decimal places
using HALF_EVEN rounding mode if `scale`

>= 0 or at integer part when `scale`

< 0.
Also known as Gaussian rounding or bankers' rounding that rounds to the nearest even number.
bround(2.5, 0) = 2, bround(3.5, 0) = 4.

`signum`

: Computes the signum of the given value.

`sign`

: Alias for `signum`

.

`sin`

: Returns the sine of the given value,
as if computed by `java.lang.Math.sin()`

. Units in radians.

`sinh`

: Returns the hyperbolic sine of the given value,
as if computed by `java.lang.Math.sinh()`

.

`sqrt`

: Computes the square root of the specified float value.

`tan`

: Returns the tangent of the given value,
as if computed by `java.lang.Math.tan()`

.
Units in radians.

`tanh`

: Returns the hyperbolic tangent of the given value,
as if computed by `java.lang.Math.tanh()`

.

`toDegrees`

: Converts an angle measured in radians to an approximately equivalent angle
measured in degrees.

`toRadians`

: Converts an angle measured in degrees to an approximately equivalent angle
measured in radians.

`unhex`

: Inverse of hex. Interprets each pair of characters as a hexadecimal number
and converts to the byte representation of number.

`atan2`

: Returns the angle theta from the conversion of rectangular coordinates
(x, y) to polar coordinates (r, theta),
as if computed by `java.lang.Math.atan2()`

. Units in radians.

`hypot`

: Computes "sqrt(a^2 + b^2)" without intermediate overflow or underflow.

`pmod`

: Returns the positive value of dividend mod divisor.
Column `x`

is divisor column, and column `y`

is the dividend column.

`shiftLeft`

: Shifts the given value numBits left. If the given value is a long value,
this function will return a long value else it will return an integer value.

`shiftRight`

: (Signed) shifts the given value numBits right. If the given value is a long
value, it will return a long value else it will return an integer value.

`shiftRightUnsigned`

: (Unigned) shifts the given value numBits right. If the given value is
a long value, it will return a long value else it will return an integer value.

`conv`

: Converts a number in a string column from one base to another.
