7.2.3 Integral Calculation Functions
Table 7.2.3.1 below lists the integral calculation functions.
7.2.4 long long Type Calculation Functions
Table 7.2.4.1 below lists the long long type calculation functions.
∗1 The long long comparison function returns the following values according to the result of op1 - op2.
∗2 Bits are scanned for logic 1 beginning with the LSB, and the position of the first bit found with the value 1 is
