IEEE-754 Floating Point Converter
Wikipedia has a nice page on the floating point format (the various IEEE-754 ones).
0x41100000
0b010000010001000000....
0 10000010 001000000....
Implied 1
0 10000010 1.001000000....
0x82 = 130
0 130 1.0010000
sign bit is zero so positive number
2 to the exponent 130-127 = 2 to the power 3.
So we move the &quot;decimal&quot; (binary) point over 3
1.001000000....
10.01000000....
100.1000000....
1001.000000....

so
0x41100000
is 1001.00000......
which is 9.0
Quite simple when you look at the format (for normal encodings):
(-1)^sign x 2^(exponent-127) x 1.fraction
