Unformatted text preview: uld be to input the decimal string 0.1 directly, either in the program
itself or in the input to the program. The compiler or interpreter then calls a
standard input-handling procedure which generates machine instructions to
15 convert the decimal string to its binary representation and store the correctly
rounded result in memory or a register. Alternatively, the integers 1 and 10
might be input to the program and the ratio 1/10 generated by a division
operation. In this case too, the input-handling program must be called to
read the integer strings 1 and 10 and convert them to binary representation.
Either integer or oating point format might be used for storing these values
in memory, depending on the type of the variables used in the program, but
these values must be converted to oating point format before the division
operation computes the ratio 1/10 and stores the nal oating point result.
From the point of view of the underlying hardware, there are relatively
few operations which can be done on oating point numbers. These inclu...
