Computing

   The mathematical conventions in QBASIC are 2^(1/2) for , SQR(13) for , LOG(2) for the natural logarithm , etc. With these, one can use QBASIC as a calculator. For instance the instruction
PRINT LOG(1+2^(1/2))
will print the decimal value of the expression . This probably is the simplest program to begin with. It is so short that there is no point in saving it.

The real power comes from repetitive operations explained in Section .
