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 |

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;
