Comparison Operators

Description

Used to compare expressions.

Syntax

result = expression1 comparisonoperator expression2

Comparison operators have these parts:

Part	Description

result

Any numeric variable.

expression1

Any expression.

comparisonoperator

Any comparison operator.

expression2

Any expression.

Returns

Number

Remarks

The following table contains a list of the comparison operators and the conditions that determine whether result is True, False.

Operator	Description	True if	False If
<	Less than	expression1 < expression2	expression1 >= expression2
<= or =<	Less than or equal to	expression1 <= expression2	expression1 > expression2
>	Greater than	expression1 > expression2	expression1 <= expression2
>= or =>	Greater than or equal to	expression1 >= expression2	expression1 < expression2
=	Equal to	expression1 = expression2	expression1 <> expression2
<>	Not equal to	expression1 <> expression2	expression1 = expression2

When comparing two expressions, you may not be able to easily determine whether the expressions are being compared as numbers or as strings. thinBasic performs internal conversions in order to determine correct values. In general it will mostly depend from what is expected.

For example:

•	if a string expression is expected, comparison will take place comparing strings. All numbers or number returned by functions calling will be converted to strings;

•	if a numeric expression is expected, comparison will take place comparing numbers. All strings or strings returned by functions calling will be converted to numbers;
