Arithmetic and String Operators in Standard Programs

Standard supports all common arithmetic operators and follows the standard order of operations (PEMDAS — Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). Unlike languages such as Java, Standard does not suffer from floating-point rounding issues, so your numeric results are precise. Because Standard does not use = for assigning values to variables, all arithmetic operations and string concatenation must be written inside parentheses.

radius 7
circ (3.14159 * radius ^ 2)
print circ

Modulo

Use the % operator to compute the remainder of a division:

dividend (65 % 5)
print dividend #prints 0

String Operations

Standard gives you two ways to concatenate strings: the . operator and the + operator. The behavior of each differs when the operands look like numbers.

in firstname "What is your name?"
print ("Hello ".firstname)
print ("5" + "7") #Prints 12
print ("5" + "Hello") #prints "5Hello"

Prefer . over + for string concatenation. When both operands of + contain only numeric characters, Standard treats them as numbers and adds them instead of joining them as strings — which can produce unexpected results. Using . always concatenates, regardless of the content.
