chore(math): tune cubic-bezier precison to 10bits

Browse Source 
10 bits is already enough for normally used ease functions(ease, ease-in, ease-out, ease-in-out).
14 bits provides more accuracy and requires additional shift operation.
>14bits provices more accuracy but requires 64bit calculation and additional shift operation.

Add normally used ease function in test.
