Common rounding

# construct data inputs
ar_fl_exa = np.array([0.4334, 0.5183, 0.0454, 0.0027, 0.0002])
ls_st_numformated_common = pyfan_amto_round.ff_decimal_rounder(ls_fl_num2format=ar_fl_exa, it_or_dc_round_decimal=2)
print(f'{ls_st_numformated_common=}')

Out:

ls_st_numformated_common=['0.43', '0.52', '0.05', '0.00', '0.00']

Uncommon rounding by number size with fractions

dc_round_decimal = {0.001:4, 0.01:3, 0.1:2, float("inf"):2}
ls_st_numformated_uncommon = pyfan_amto_round.ff_decimal_rounder_uncommon(ls_fl_num2format=ar_fl_exa,
                                                                          dc_round_decimal=dc_round_decimal)
print(f'{ls_st_numformated_uncommon=}')

Out:

ls_st_numformated_uncommon=['0.43', '0.52', '0.05', '0.003', '0.0002']

Uncommon rounding by number size test 2 with large numbers

ls_fl_num2format = [0.0012345, 0.12345, 12.345, 123.45, 1234.5, 123456.789]
dc_round_decimal = {0.1:4, 1:3, 100:2, float("inf"):0}
ls_st_numformated_large_uncommon = pyfan_amto_round.ff_decimal_rounder_uncommon(ls_fl_num2format=ls_fl_num2format,
                                                                                dc_round_decimal=dc_round_decimal)
print(f'{ls_st_numformated_large_uncommon=}')
