Function Documentation

◆ g1p_isInf()

__device__ bool g1p_isInf ( const g1p_t & p )

Check if the value stored in p is the the/any point at infinity. This implementation uses (0, 1, 0) as the point at infinity. Alternatively, the macro G1P_ANYINF allows the point at infinity to be represented as (0, y, 0) where y!=0.

The algebra used in this library sets the point at infinity to (0, 1, 0) (or (0, y, 0)), instead of the usual (1, 1, 0) used in other libs, due to following the Algorithm 7 in eprint 2015-1060.

Parameters

[in] p

Returns: bool 1 if the p is the point at infinity.
