List of buitlt-in functions
- abs ⇒ Absolute value, Usage:
abs(x)
- Returns the absolute value of a number. The absolute value of a number is the number without its sign.
- E.g.: abs(-1) = 1
- E.g.: abs(1) = 1
- acos ⇒ Inverse cosine function working with radians, Usage:
acos(x)
- The arccosine function is the inverse function of the cosine function and calculates the angle for a given cosine. X must be in the [-1..1] range. The result is an angle expressed in radians.
- E.g.: acos(0.1) = 1.47063
- acosD ⇒ Inverse cosine function working with degrees, Usage:
acosD(x)
- For values of X in the interval [-1, 1], acosd(X) returns values in the interval [0, 180]
- E.g.: acosD(-1) = 180
- acosh ⇒ Inverse Hyperbolic cosine function, Usage:
acosh(x)
- Returns the inverse hyperbolic cosine of a number. The number must be greater than 1.
- E.g.: acosh(2) = 1.31696
- asin ⇒ Inverse sine function working with radians, Usage:
asin(x)
- It returns the inverse sine of a value, given a ratio of a triangle's opposite side over its hypotenuse. The
asin()
function is a trigonometric function that returns the inverse sine of a number between-1
and1
. The function contains a single calculation that returns the number of radians representing an<angle>
between-90deg
and90deg
. - E.g.: asin(-1) = -1.5708
- It returns the inverse sine of a value, given a ratio of a triangle's opposite side over its hypotenuse. The
- asinD ⇒ Inverse sine function working with degrees, Usage:
asinD(x)
- The function accepts both real and complex inputs. For real values of X in the interval [-1, 1], asind(X) returns values in the interval [-90, 90].
- E.g.: asinD(1) = 90
- asinh ⇒ Inverse Hyperbolic sine function, Usage:
asinh(x)
- Returns the inverse hyperbolic sine of the elements of
X
. All angles are in radians. - E.g.: asinh(90) = 5.19299
- Returns the inverse hyperbolic sine of the elements of
- atan ⇒ Inverse tangent function working with radians, Usage:
atan(x)
- atanD ⇒ Inverse tangent function working with degrees, Usage:
atanD(x)

max(arg 1; arg 2; ... arg n)
- min ⇒ Min of all arguments, Usage:
min(arg 1; arg 2; ... arg n)
- radTodeg ⇒ Converts radians to degrees, Usage:
radTodeg(angle 0 in radians)
- rint ⇒ Round to nearest integer, Usage:
