b = (b – 5) + 3
b = b – (5 + 3)
The parentheses indicate that the expression within should be evaluated first after which the result may
be used as an operand in another operation.
2.4.3 Arithmetic Operators
The arithmetic operators are listed in the table below along with the permitted operand types. The result
is the same type as the operands.

Notes:
¹ In BasicX mode, operating on UnsignedLong is not supported.
² The result will be the same type as the left operand. In BasicX mode, the left
operand must be Single and the right operand must be either Single or Integer.
For Single operands, dividing by zero produces a special value indicating either positive or negative
infinity depending on the sign of the dividend. Dividing 0.0 by 0.0 produces a special value called NaN,
representing a value that is “Not a Number”. Similarly, performing the Mod operation with Single values
using a divisor of zero produces a NaN. For all other operand types the result of using a zero divisor for
either division or Mod is undefined. The System Library function SngClass() returns a value indicating
the general classification of a value of type Single. See the description of SngClass() in the System
Library Reference Manual for more information.
