Q. Number used as operand data type?

Numbers: All machine languages comprise numeric data types. Numeric data generally use one of the three representations:

o Floating point numberssingle precision (1 sign bit, 8 exponent bits, 23 mantissa bits) and double precision (1 sign bit, 11 exponent bits, 52 mantissa bits).

o Fixed point numbers (signed or unsigned).

o Binary Coded Decimal Numbers.

Most of the machines deliver instructions for performing arithmetic operations on fixed point and floating-point numbers. Though there is a limit in magnitude of numbers due to underflow and overflow.
