Operator <= (Less Than Or Equal)

Compares an expression less than or equal to another expression

Syntax

Declare Operator <= ( ByRef lhs As Byte, ByRef rhs As Byte ) As Integer
Declare Operator <= ( ByRef lhs As UByte, ByRef rhs As UByte ) As Integer
Declare Operator <= ( ByRef lhs As Short, ByRef rhs As Short ) As Integer
Declare Operator <= ( ByRef lhs As UShort, ByRef rhs As UShort ) As Integer
Declare Operator <= ( ByRef lhs As Integer, ByRef rhs As Integer ) As Integer
Declare Operator <= ( ByRef lhs As UInteger, ByRef rhs As UInteger ) As Integer
Declare Operator <= ( ByRef lhs As LongInt, ByRef rhs As LongInt ) As Integer
Declare Operator <= ( ByRef lhs As ULongInt, ByRef rhs As ULongInt ) As Integer

Parameters

• lhs
• rhs
• T

Description

Operator <= (Less than or Equal) is a binary operator that compares an expression less than or equal to another expression and returns the result - a boolean value in the form of an Integer: negative one (-1) for true and zero (0) for false. The arguments are not modified in any way.

When this operator is applied to string type data, then a lexicographic/alphabetic order comparison is performed (ordered from the numeric ASCII values of the characters of the two strings).

This operator can be overloaded to accept user-defined types as well.

Return Value

Returns negative one (-1) if the left-hand side expression is less than or equal to the right-hand side expression, or zero (0) if greater than.

Remarks

Usage

result = lhs <= rhs

Dialect Differences

• In the -lang qb dialect, this operator cannot be overloaded.

Differences from QB

• none

Examples

Operator > (Greater than) is complement to Operator <= (Less than or Equal), and is functionally identical when combined with Operator Not (Bit-wise Complement).

If (69 <= 420) Then Print "(69 <= 420) is true."

   If Not (60 > 420) Then Print "not (420 > 69) is true."
