Numeric Expressions

Numeric expressions in BASIC-256 come in two varieties; 1) integer, and 2) floating point numbers. They are created by using Arithmetic Operators and functions with Numeric Constants and Variables.

Integer Expressions

Integer Expressions are expressions that return a whole number.

Examples include:

Integer Expressions
10
ABS(-2345)
int(9.987)
5*8

Positive integer values may also be expressed in binary (base 2), octal (base 8), and hexadecimal (base 16). Precede binary values with 0b (0b1110 = 14), octal with 0o (0o177 = 127), and hexadecimal with 0x (0xff = 255).

Floating Point Expressions

Expressions that return a decimal number, even if it ends in .0, are known as floating point expressions.

Examples include:

Floating Point Expressions
3/7
float(56)
sin(2*pi)

Very large and small floating point numbers may also be represented in scientific E notation (added in version 0.9.9.46). http://en.wikipedia.org/wiki/Scientific_notation
