THE PACKAGE JAVA.LANG

java.lang.Float

20.9

If the argument is any value in the range

0x7f800001

 through

0x7fffffff

 or

in the range

0xff800001

 through

0xffffffff

, the result will be NaN. (All

IEEE 754 NaN values are, in effect, lumped together by the Java language

into a single value called NaN.)

In all other cases, let

s

,

e

, and

m

 be three values that can be computed from the

argument:

int s = ((bits >> 31) == 0) ? 1 :  1;

int e = ((bits >> 23) & 0xff);

int m = (e == 0) ?

(bits & 0x7fffff) << 1 :

(bits & 0x7fffff) | 0x800000;

Then the floating point result equals the value of the mathematical expression

s

m

2

e

  150

.
