3.6 Real-valued arithmetic operators
The arithmetic operators are presented using C++ notation. For
instance operator+(x,y)
refers to the binary addition operator and
operator-(x)
to the unary negation operator. In Stan programs,
these are written using the usual infix and prefix notations as x + y
and -x
, respectively.
3.6.1 Binary infix operators
real
operator+
(real x, real y)
Return the sum of x and y. (x+y)=operator+(x,y)=x+y
Available since 2.0
real
operator-
(real x, real y)
Return the difference between x and y. (x−y)=operator-(x,y)=x−y
Available since 2.0
real
operator*
(real x, real y)
Return the product of x and y. (x∗y)=operator*(x,y)=xy
Available since 2.0
real
operator/
(real x, real y)
Return the quotient of x and y. (x/y)=operator/(x,y)=xy
Available since 2.0
real
operator^
(real x, real y)
Return x raised to the power of y. (x∧y)=operator∧(x,y)=xy
Available since 2.5
