17 Formats a (floating point) number or a fraction as a decimal number. If a 'digits' option is set, the number of digits before the decimal point is increased up to the given count by preceding it with zeros. The digits after the decimal point are adjusted by the 'precision' parameter. The 'decimal_shift' parameter is useful, when fixed precision decimal numbers are stored as integers, as the given value will be divided by 10 to the power of the 'decimal_shift' value prior to formatting. Setting 'decimal_shift' to true will use the 'precision' value as 'decimal_shift'.
