Structure - Math
As with most BASIC implementations, MBasic includes a full complement of math and comparison
functions. MBasic supports 32 bit integer math, both signed and unsigned. It also supports fl oating
point math, signed or unsigned. A signed value denotes whether the resulting value is positive or
negative.
Floating point math can be processor intensive. This should be considered whenever making a
decision in creating a program with math functions. There are numerous cases where fl oating
point math is required. Hence, the fl exibility of the BasicATOM when compared to other available
processors.
Number Bases
Although all calculations are handled internally in binary, users can refer to numbers as decimal,
hexadecimal or binary, whichever is most convenient for the programmer. For example, the number
2349 can be referred to as:
2349 Decimal
0x092D Hexadecimal
%100100101101 Binary
Leading zeros are not required for hex or binary numbers, but may be used if desired. When using
signed integers (sbyte, sword, slong) it is probably a good idea to stick to decimal notation to avoid
confusion.
Math and Operators
Operators are what makes math work, by performing a function. An example of an operator would
be + (Addition), - (Subtraction), * (Multiplication) and / (Division). All these symbols represent an
operation to be performed. However, the operators need something to do, so we add operands which
are better known as arguments. Math arguments are the values used in an expression.
In the following section you will see the word “expression” used many times. This refers to something
like 1+2. The expression 1+2 has one operator (+) and two arguments(1 and 2) or operands.
