If the result is
0, there is no point in having ascale.In the case of functions, when converting to
string, the decimal part is automatically filled with0to match the setscale, sobc_numitself does not need to hold an extrascale.Even with the
Numberclass, objects retain thescale, sobc_numitself does not need to retain it.If
bc_numholds an unnecessaryscale, subsequent calculations using theNumberclass will result in unnecessary calculations.notes
The only exception is
round(), which is designed so that then_scaleofbc_numaffects the return value.So I changed it so that it doesn't affect the return value.
