pyfan.amto.numeric.round¶
The pyfan.amto.numeric.round provides decimal rounding for float arrays.
Given an array of numbers, provide conditional decimal formatting rounding via fstring. This is used by table function to generate table specific rounding rules.
For example, a table with birthweight in grams, and ratios, might have 2 decimals for numbers less than 1, but no decimals for numbers larger than 1000 (which are the grams).

pyfan.amto.numeric.round.ff_decimal_rounder(ls_fl_num2format, it_or_dc_round_decimal, verbose=False)[source]¶ Decimal rounding function with common decimal formatting
- Parameters
- ls_fl_num2formatlist of float
- it_or_dc_round_decimalint or dict
the number of decimal points to keep. If dict, same as dc_round_decimal for
ff_decimal_rounder(). If decimal, generate dict that provides common formating
- Returns
- list of str
Decimal formatted string outputs

pyfan.amto.numeric.round.ff_decimal_rounder_uncommon(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}, verbose=False)[source]¶ Decimal rounding function with conditional formatting by number size
Given an array of numbers, format and return as a list of string, with different decimal formatting given different number sizes.
- Parameters
- ls_fl_num2formatlist of float
list of numbers of approximate to decimals
- dc_round_decimaldict
dict incremental formatter. For example, for the default, if below 0.1 keep 4 decimals, If below 1 keep 3, if below 100 keep 2, if otherwise above, then keep 0 decimals Loop over formatter.
- Returns
- list of str
Decimal formatted string outputs
