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

Name		Description
`lhs`		The left-hand side expression to compare to.
`rhs`		The right-hand side expression to compare to.
`T`		Any pointer type.

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.

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.

Remarks

Usage



result = lhs <= rhs

Dialect Differences

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

Example

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."
