The and operator combines two conditions into one, which will be true if both sides are true, and false otherwise. You can create these conditions with the relational operators =, , >, , <, and , with functions such as isPrime(), pxlTest(), and ptTest(), or with any other expression that returns 'true' or 'false'. Other operators for dealing with conditions are or, xor, and not.

:2+2=4 and 1=0
:2+2=4 and 1+1=2

The operator can also be applied to integers, treating them as 32-bit signed integers (larger integers will be truncated to fit) expressed in binary. The bits will be matched up, and "and" will be applied to the bits individually — a bit in the result will be 1 if the two corresponding bits of the original integers were 1, and 0 otherwise.

:(0b11111100 and 0b00111111)▶Bin
:1000 and 512

In complicated logical expressions (both with conditions and with integers), "and" has greater priority than the others ("or" and "xor"). For instance, X or Y and Z will be interpreted as X or (Y and Z).

Error Conditions

60 - Argument must be a Boolean expression or integer happens when the data type is incorrect (or mismatched).
