Single Precision Real

This format would appear in memory as:

1-bit sign Þeld	(1 binary digit)
8-bit biased exponent Þeld	(2 hex digits. Bias = $7F)
23-bit fraction Þeld	(6 hex digits)

A single precision number takes 4 bytes in memory.

Double Precision Real

This format would appear in memory as:

1-bit sign Þeld	(1 binary digit)
11-bit biased exponent Þeld	(3 hex digits. Bias = $3FF)
52-bit fraction Þeld	(13 hex digits)

A double precision number takes 8 bytes in memory.

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