Line 15:

A BID number has three fields, the sign the exponent and the magnitude.

If the top bits of the exponent are less than or equal binary 1110:

If

''s'' = +1 (positive numbers) when the sign bit is 0

Line 25:

''m'' = ''significand''.

The number has the value:

''v'' = ''s'' × 10''^e'' × ''m''

The ''exponent'' and ''significand'' are stored as binary integers.

If the top bits of the exponent are greater than 1110, the encoding is not for a value. If the top five bits of the exponent field have the encoding 11110 binary, the number represented is + or - infinity, the sign bit determines which. Nan is represented by the tops five bits of the exponent field being set to 11111.
