The model set for reals, in general, is defined as one of the following:
The following values apply to this model set:
REAL(4) | IEEE S_floating | 24 |
REAL(8) | IEEE T_floating | 53 |
REAL(16) | IEEE X_floating | 113 |
emin | emax | ||
---|---|---|---|
REAL(4) | IEEE S_floating | -125 | 128 |
REAL(8) | IEEE T_floating | -1021 | 1024 |
REAL(16) | IEEE X_floating | -16381 | 16384 |
For x = 0, its exponent e and digits fk are defined to be zero.
The model set for single-precision real (REAL(4)) is defined as one of the following:
The following example shows the general real model for x = 20.0 using a base (b) of 2:
