##//lhs//##
The left-hand side expression to compare to.
##//rhs//##
The right-hand side expression to compare to.
##//T//##
Any pointer type.

{{fbdoc item="ret"}}
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.

{{fbdoc item="desc"}}
**##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 ##[[KeyPgInteger|Integer]]##: negative one (-1) for true and zero (0) for false. The arguments are not modified in any way.

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

{{fbdoc item="ex"}}
##[[KeyPgOpGreaterThan|Operator >]]## (Greater than) is complement to **##Operator <=## (Less than or Equal)**, and is functionally identical when combined with ##[[KeyPgOpNot|Operator Not]]## (Bit-wise Complement).

{{fbdoc item="filename" value="examples/manual/operator/less-than-or-equal.bas"}}%%(freebasic)
if (69 <= 420) then print "(69 <= 420) is true."
if not (60 > 420) then print "not (420 > 69) is true."
%%

{{fbdoc item="lang"}}
- In the //[[CompilerOptlang|-lang qb]]// dialect, this operator cannot be overloaded.

{{fbdoc item="diff"}}
- none

{{fbdoc item="see"}}
- ##[[KeyPgOpGreaterThan|Operator >]]## (Greater than)
