Section 3.4 says:

Note. The value 5A..99 is a hexadecimal 32-bit constant, written with the high-order digit first. This constant represents the square root of 2. The octal value of this constant is 013240474631. The value 6E..A1 is a hexadecimal 32-bit constant, written with the high-order digit first. This constant represents the square root of 3. The octal value of this constant is 015666365641.

It should say:

Note. The value 5A..99 is a hexadecimal 32-bit constant, written with the high-order digit first. This constant represents the square root of 2 divided by 4. The octal value of this constant is 013240474631. The value 6E..A1 is a hexadecimal 32-bit constant, written with the high-order digit first. This constant represents the square root of 3 divided by 4. The octal value of this constant is 015666365641.

Notes:

More precisely, the value 5A..99 is a result of the formula: HEX(TRUNC((SQRT(2)/4)*2^32)), where SQRT represents the square root, TRUNC is truncation of the fractional part, HEX is a hexadecimal representation. Similarly, the value 6E..A1 = HEX(TRUNC((SQRT(3)/4)*2^32)).
