Relational Expressions

C++ like relational expressions are defined for use as boolean arguments to procedures and for use with conditional expressions. The relational operators are:

"=="

<true> if the expressions are equal.

"!="

<true> if the expressions are not equal.

"<"

<true> if the left hand expression (LHE) is less than the right hand expression (RHE).

">"

<true> if the LHE is greater than the RHE.

"<="

<true> if the LHE is less than or equal to the RHE.

">="

<true> if the LHE is greater than or equal to the RHE.

"&&"

<true> if both expressions are non-zero or <true>.

"||"

<true> if either expression is non-zero or <true>.

        1+3 >= 3**4;


Both arguments to "==", "!=", "<",
">", ">=", and "<=" must be
numeric (integers, floats, or expressions returning integers or
floats).  The arguments to "&&" and "||" may be
numeric or boolean.
