Bool Type
The bool type is intended to store the logical values of true or false, numeric representation of them is 1 or 0, respectively.
Examples:
bool a = true;
bool b = false;
bool c = 1; |
The internal representation is a whole number 1 byte large. It should be noted that in logical expressions you can use other integer or real types or expressions of these types - the compiler will not generate any error. In this case, the zero value will be interpreted as false, and all other values - as true.
Examples:
int i=5;
double d=-2.5;
if(i) Print("i = ",i," and is set to true");
else Print("i = ",i," and is set to false");
if(d) Print("d = ",d," and has the true value");
else Print("d = ",d," and has the false value");
i=0;
if(i) Print("i = ",i," and has the true value");
else Print("i = ",i," and has the false value");
d=0.0;
if(d) Print("d = ",d," and has the true value");
else Print("d = ",d," and has the false value");
//--- Execution results
// i= 5 and has the true value
// d= -2.5 and has the true value
// i= 0 and has the false value
// d= 0 and has the false value |
