Mathematical Functions

abs()

Returns the absolute value of a given number.

GQL
RETURN abs(-2.32)

Result:

ceil()

Rounds a given number up to the nearest integer.

NOTE

ceiling() is a synonym to ceil().

GQL
For item in [-2.92, 4.2]
RETURN ceil(item)

Result:

exp()

Computes the value of Euler's number 𝑒 raised to the power of a given number, where 𝑒 is approximately equal to 2.71828.

GQL
RETURN exp(2)

Result:

floor()

Rounds a given number down to the nearest integer.

GQL
For item in [-2.92, 4.2]
RETURN floor(item)

Result:

ln()

Computes the natural logarithm of a given number, i.e., the logarithm to the base 𝑒 (Euler's number, approximately 2.71828).

GQL
RETURN ln(100)

Result:

log()

Computes the logarithm of a specified number with respect to a given base.

GQL
RETURN log(2, 8)

Result:

log10()

Computes the base 10 logarithm of a given number.

GQL
RETURN log10(100)

Result:

mod()

Computes the modulus, or the remainder when one number is divided by another.

GQL
RETURN mod(9.2, 2)

Result:

pi()

Returns the mathematical constant π (pi) approximately equal to 3.14159. Pi is the ratio of a circle's circumference to its diameter in Euclidean geometry.

GQL
RETURN pi()

Result:

power()

Raises a number to the power of another number.

GQL
RETURN power(2, 4)

Result:

round()

Returns the nearest value of a given number, rounded to a specified position of digits. If two nearest values are equidistant, it returns the one with the larger absolute value.

GQL
RETURN round(3.1415926, 3)

Result:

sqrt()

Computes the square root of a given number.

GQL
RETURN sqrt(16)

Result:
