SQR in SmileBasic V1 is identical to that in V2.
SQR(N) is a function which takes one numerical parameter,
N, and returns its square root. If
N is negative, the system gives an
Illegal function call (SQR) error; if
N is a string, the system gives a
Type Mismatch (SQR) error; and if two parameters are used, the system gives a
Missing operand (SQR) error.
Another way to calculate the square root of
N is to use the expression
SQR in SmileBasic V3 is identical to that in V2.
