Mathematical Functions
This page covers mathematical operators and functions available in Rockset.
All functions accept arguments of types int and float. The return type is float, unless otherwise specified.
Operators
Rockset supports the basic arithmetic operators shown below on any combination of int and float values.
| Operator | Description |
|---|---|
+ x | positive sign |
- x | negative sign |
x + y | addition |
x - y | subtraction |
x * y | multiplication |
x / y | division |
x % y | modulo (remainder) |
Basic Functions
ABS
ABS(x)Returns absolute value of x. Return type is the same as input.
CEIL
CEIL(x)Returns the smallest integral value that is not less than x.
CEILING
CEILING(x)Alias of CEIL.
GREATEST
GREATEST(a, b, c, ...)Returns the argument that is greater than or equal to all other arguments.
LEAST
LEAST(a, b, c, ...)Returns the argument that is less than or equal to all other arguments.
SIGN
SIGN(x)Returns sign of x as an integer: -1 if x is negative, 0 if x is zero,
1 if x is positive.
FLOOR
FLOOR(x)Returns the largest integral value that is not greater than x.
Log and Exponential Functions
EXP
EXP(x)Computes e to the power of x.
POW
POW(x, y)Computes x to the power of y.
POWER
POWER(x, y)Alias of POW.
SQRT
SQRT(x)Computes the square root of x.
LN
LN(x)Computes the natural logarithm of x.
LOG10
LOG10(x)Computes the base-10 logarithm of x.
LOG2
LOG2(x)Computes the base-2 logarithm of x.
Trigonometric Functions
ACOS
ACOS(x)Computes the arc cosine of x.
ACOSH
ACOSH(x)Computes the inverse hyperbolic cosine of x.
ASIN
ASIN(x)Computes the arc sine of x.
ASINH
ASINH(x)Computes the inverse hyperbolic sine of x.
ATAN
ATAN(x)Computes the arc tangent of x.
ATAN2
ATAN2(y, x)Computes the arc tangent of y / x, but with proper sign for quadrant
correction. That is, correctly computes the angle θ when converting from the
Cartesian coordinates (x, y) to the polar coordinates (r, θ).
ATANH
ATANH(x)Computes the inverse hyperbolic tangent of x.
COS
COS(x)Computes the cosine of x.
COSH
COSH(x)Computes the hyperbolic cosine of x.
HYPOT
HYPOT(x, y)Computes SQRT(x*x + y*y), that is, the length of the hypothenuse of a
right-angled triangle with sides of lengths x and y, or the distance
between the point at coordinates (x, y) and origin.
SIN
SIN(x)Computes the sine of x.
SINH
SINH(x)Computes the hyperbolic sine of x.
TAN
TAN(x)Computes the tangent of x.
TANH
TANH(x)Computes the hyperbolic tangent of x.
