Struct DecimalFormatF64 

pub struct DecimalFormatF64(pub usize, pub usize, pub f64);

This struct allows you to print a specific number of digits before the decimal point, and after the decimal point.

This exists because the base format trait allows you to specify a width and a precision. However, in a fractional number, the width applies to the WHOLE number, including the fractional component, and doesn’t zero-pad effectively.

• The first parameter is the number of zero-padded digits before the decimal point.
• The second parameter is the number of zero-padded digits after the decimal point.

Example:

use irox_tools::fmt::DecimalFormatF64;
assert_eq!("00.1235", format!("{}", DecimalFormatF64(2,4,0.1234567)));

Tuple Fields

0: usize

1: usize
