smartOp.cmp

Compare left and right using op.

Unlike the standard integer comparison operator, this function correctly handles negative values in signed/unsigned comparisons.
Like the standard operator, comparisons involving any floating-point nan value always return false.

Direct comparisons between boolean values and numeric ones are forbidden. Make the intent explicit:

numeric == cast(N)boolean
(numeric != 0) == boolean

bool cmp(const N left, const M right)
template smartOp(IntFlagPolicy policy)

)
int cmp(const N left, const M right)

Examples

1 import checkedint.sticky : smartOp; // smartOp.cmp() never throws
2 
3 assert(uint.max == -1);
4 assert( smartOp.cmp!"!="(uint.max, -1));
5 assert(-3156 > 300u);
6 assert( smartOp.cmp!"<"(-3156, 300u));
7 
8 assert(!smartOp.cmp!"<"(1, real.nan));
9 assert(!smartOp.cmp!"<"(real.nan, 1));
