+** result into separate integer values:
+**
+** ieee754_mantissa(45.25) -> 181
+** ieee754_exponent(45.25) -> -2
+**
+** These functions convert binary64 numbers into blobs and back again.
+**
+** ieee754_from_blob(x'3ff0000000000000') -> 1.0
+** ieee754_to_blob(1.0) -> x'3ff0000000000000'
+**
+** In all single-argument functions, if the argument is an 8-byte blob
+** then that blob is interpreted as a big-endian binary64 value.
+**
+**
+** EXACT DECIMAL REPRESENTATION OF BINARY64 VALUES
+** -----------------------------------------------
+**
+** This extension in combination with the separate 'decimal' extension
+** can be used to compute the exact decimal representation of binary64
+** values. To begin, first compute a table of exponent values:
+**
+** CREATE TABLE pow2(x INTEGER PRIMARY KEY, v TEXT);
+** WITH RECURSIVE c(x,v) AS (
+** VALUES(0,'1')
+** UNION ALL
+** SELECT x+1, decimal_mul(v,'2') FROM c WHERE x+1<=971
+** ) INSERT INTO pow2(x,v) SELECT x, v FROM c;
+** WITH RECURSIVE c(x,v) AS (
+** VALUES(-1,'0.5')
+** UNION ALL
+** SELECT x-1, decimal_mul(v,'0.5') FROM c WHERE x-1>=-1075
+** ) INSERT INTO pow2(x,v) SELECT x, v FROM c;
+**
+** Then, to compute the exact decimal representation of a floating
+** point value (the value 47.49 is used in the example) do:
+**
+** WITH c(n) AS (VALUES(47.49))
+** ---------------^^^^^---- Replace with whatever you want
+** SELECT decimal_mul(ieee754_mantissa(c.n),pow2.v)
+** FROM pow2, c WHERE pow2.x=ieee754_exponent(c.n);
+**
+** Here is a query to show various boundry values for the binary64
+** number format:
+**
+** WITH c(name,bin) AS (VALUES
+** ('minimum positive value', x'0000000000000001'),
+** ('maximum subnormal value', x'000fffffffffffff'),
+** ('mininum positive nornal value', x'0010000000000000'),
+** ('maximum value', x'7fefffffffffffff'))
+** SELECT c.name, decimal_mul(ieee754_mantissa(c.bin),pow2.v)
+** FROM pow2, c WHERE pow2.x=ieee754_exponent(c.bin);
