4. The sign field, the exponent field, and at least the first digit of

the mantissa field must be present (any unspecified digits in
the mantissa field are set to zero).

5. Each field must be separated from adjacent fields by an

underscore.

6. All the digit positions in the sign and exponent fields must be

present.

Single Precision Real

This format would appear in memory as:

A single precision number takes 4 bytes in memory.

Double Precision Real

This format would appear in memory as:

A double precision number takes 8 bytes in memory.

Note

The single and double precision formats have an
implied integer bit (always 1).

1-bit sign field

(1 binary digit)

8-bit biased exponent field

(2 hex digits. Bias = $7F)

23-bit fraction field

(6 hex digits)

1-bit sign field

(1 binary digit)

11-bit biased exponent field

(3 hex digits. Bias = $3FF)

52-bit fraction field
