Arithmetic functions in dashboard function expressions
The following arithmetic functions are supported in dashboard function expressions:
abs()
double abs(double a)
Returns the absolute value of a double value.
acos()
double acos(double a)
Returns the arc cosine of an angle, in the range of 0.0 through pi.
asin()
double asin(double a)
Returns the arc sine of an angle, in the range of -pi/2 through pi/2.
atan()
double atan(double a)
Returns the arc tangent of an angle, in the range of -pi/2 through pi/2.
atan2()
double atan2(double y, double x)
Converts rectangular coordinates (x, y) to polar (r, theta).
ceil()
double ceil(double a)
Returns the smallest (closest to negative infinity) double value that is greater than or equal to the argument and is equal to a mathematical integer.
cos()
double cos(double a)
Returns the trigonometric cosine of an angle.
exp()
double exp(double a)
Returns Euler's number e raised to the power of a double value.
floor()
double floor(double a)
Returns the largest (closest to positive infinity) double value that is less than or equal to the argument and is equal to a mathematical integer.
IEEEremainder()
double IEEEremainder(double f1, double f2)
Computes the remainder operation on two arguments as prescribed by the IEEE 754 standard.
log()
double log(double a)
Returns the natural logarithm (base e) of a double value.
max()
double max(double a, double b)
Returns the greater of two double values.
min()
double min(double a, double b)
Returns the smaller of two double values.
pow()
double pow(double a, double b)
Returns the value of the first argument raised to the power of the second argument.
random()
double random()
Returns a double value with a positive sign, greater than or equal to 0.0 and less than 1.0.
rint()
double rint(double a)
Returns the double value that is closest in value to the argument and is equal to a mathematical integer.
round()
long round(double a)
Returns the closest long value to the argument.
sin()
double sin(double a)
Returns the trigonometric sine of an angle.
sqrt()
double sqrt(double a)
Returns the correctly rounded positive square root of a double value.
tan()
double tan(double a)
Returns the trigonometric tangent of an angle.
toDegrees()
Converts an angle measured in radians to an approximately equivalent angle measured in degrees.
