## Arguments

x

Column to compute on. In shiftLeft, shiftRight and shiftRightUnsigned, this is the number of bits to shift.

...

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.

## Details

abs: Computes the absolute value.

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

acosh: Computes inverse hyperbolic cosine of the input column.

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

asinh: Computes inverse hyperbolic sine of the input column.

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

atanh: Computes inverse hyperbolic tangent of the input column.

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().

cot: Returns the cotangent of the given value.

csc: Returns the cosecant of the given value.

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.

degrees: 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.

radians: 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.

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.

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: (Unsigned) 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: (Unsigned) 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.

sec: Returns the secant of the given value.
