The keywords "true" and "false" are the default boolean values. But, many functions prefer to return boolean "1" or "0" instead of "true" or "false". It is very important to note that having a function return a numerical 1 or 0 is not the same as a boolean "1" or "0". To make a number or array of numbers a boolean use the logical() function. logical() will convert any non-zero number to a boolean "1" and any zero entries a boolean "0". |
