TEST	(	IntmathDeathTest	,
		Log2iDeath	)

This is testing the assertions: what if invalid arguments are provided to log2i:

1) value = 0 2) value < 0 3) value is not a power of 2

TEST	(	IntmathTest	,

This is testing if log2i actually works.

at every iteration value is multiplied by 2 (left shift) and expected is incremented by one. This until value reaches becomes negative (by left shifting) which is when expected points to the MSB
