Elemental Intrinsic Function (Generic): Returns the parity of the integer argument.
Syntax
result = POPPAR (i)
i
(Input) Must be of type integer or logical.
Results
The result type is the same as i. The result value is 1 if there are an odd number of 1 bits in the binary representation of the integer I. The result value is zero if there are an even number.
POPPAR(i) is the same as 1 .AND. POPCNT(i).
The model for the interpretation of an integer value as a sequence of bits is shown in Model for Bit Data.
Example
If the value of I is B'0...00011010110', the value of POPPAR(I) is 1.
