TOBOOLEAN

conversion

Converts a value of primitive type into a boolean value.

The TOBOOLEAN function consumes a parameter from the top of the stack and pushes back its conversion to boolean. Numbers will be false if they are equal to 0 and true otherwise. Strings will be false if they are equals to '' and true otherwise.

TOBOOLEAN is available since version 1.0.5.
