This PR improves the performance of the BC extension computations for the decimal numbers with trailing zeros. Specifically we get Memory limit error while we want to raise zero with many trailing zeros to large exponent. Example: https://onlinephp.io/c/dcd86
Also it may improve other special cases of operations with number zero, like multiplying with number zero.
