i128_multiply_i64_i64()

void i128_multiply_i64_i64 ( int64_t a, int64_t b, int128_t * result )

inlinestatic

Multiply two signed 64-bit integers and store the result in a 128-bit integer.

This function performs a full precision multiplication of two signed 64-bit values. The result is guaranteed to fit in a 128-bit representation without overflow.

Parameters

a	Multiplicand.
b	Multiplier.
result	Pointer to the int128_t structure where the result will be stored.
