Operators in Logical and Arithmetic Expressions

(These operators have the same syntax and behavior as in C. The FORTRAN-style operators (.lt., .or., etc.) that were allowed in DSL version 3.1 are no longer supported in BTCL version 95.0.)

-a: negative of a
!a: logical NOT: evaluates to 1 if a is zero, 0 otherwise
~a: bit-wise complement
a+b: add a to b
a-b: subtract b from a
a*b: multiply a by b
a/b: divide a by b
a%b: remainder after dividing a by b
a&b: bit-wise AND of a and b
a|b: bit-wise OR of a and b
a^b: bit-wise exclusive OR of a and b
a==b: evaluates to 1 if a is equal to b, 0 otherwise
a!=b: evaluates to 1 if a is not equal to b, 0 otherwise
a<=b: evaluates to 1 if a is less than or equal to b, 0 otherwise
a>=b: evaluates to 1 if a is greater than or equal to b, 0 otherwise
a<b: evaluates to 1 if a is less than b, 0 otherwise
a>b: evaluates to 1 if a is greater then b, 0 otherwise
a&&b: logical AND: evaluates to 1 if a and b are nonzero, 0 otherwise
a||b: logical OR: evaluates to 1 if a or b are nonzero, 0 otherwise
a?b:c: choice: if a is nonzero then b, else c
