These number representations are used for SEL computers. They are the same as IBM 32bit format.
SEL floating point numbers are represented by one bit for the sign (S),
7 bits for the exponent, and 24 bits for the fraction. The exponent
is to the base 16 (not 2), and has a bias of 64. Because of the base
16, the fraction may have up to three leading zeros. In this manner,
some of the exponential value may be assumed by the fraction, increasing
its range, at the cost of some precision. Normalization to the leading
bit is not possible. Floating point numbers have no complement (neither
one's nor two's complement). They are in signmagnitude format (the
sign being bit 31).
SINGLE PRECISION is shown below:
SEL 32Bit Floating Point Format  
S  Exponent  Fraction (Note: the most significant three bits [23, 22, and 21] might all be zero).  
































DOUBLE PRECISION adds another 32 bits of fraction
(of decreasing significance) in the following 32bit word..
INTEGER numbers are in two's complement.
