EnDinero

// convenience shorthand for formatting f32 in spanish, it will truncate the decimals we don't want
// outputs 2 decimals for amounts > 0, and 7 decimals for amounts < 1.
// This is how we need it for our crypto market pages when dealing with some crapcoins that trade in very small amounts
use endinero::dinero_f32;
assert_eq!(endinero::dinero_f32(0.1234567), "0,123 456 7");

// convenience shorthand for formatting f64 in spanish
use endinero::dinero_f64;
assert_eq!(endinero::dinero_f64(0.22233344455566), "0,222 333 444 555 66");

Convert a float value to a user-friendly number, most often used to represent money amounts in Spanish (perhaps German and some other European locales work the same as in spanish)

assert_eq!(endinero::dinero_f32(10.111), "10,11");
assert_eq!(endinero::dinero_f32(-10.111), "-10,11");
assert_eq!(endinero::dinero_f32(0.1234567), "0,123 456 7");
assert_eq!(endinero::dinero_f64(0.2223334445556677), "0,222 333 444 555 666 77");

If you need to specify thousand separators, decimal separators, radix character, how many decimals to show for numbers > 0 or for numbers < 1 use the endinero::endinero function that receives all the parameters.

use endinero::endinero;
assert_eq!(
    endinero_f64(-1234567.456789, // amount 
                 4, // decimals for numbers > 0
                 4, // decimals for numbers < 0
                 '.', // thousands separator
                 ',', // radix separator
                 ' '), // decimals separator
    "-1.234.567,456 7"
);

If you also need to format US dollars for American english we've included endinero::money_f32 and endinero::money_f64 formatters.

// it will show only two decimals for numbers > 0
assert_eq!(money_f32(12345678.123456), "12,345,678.12");
assert_eq!(money_f32(1.123456),"1.12");

// it will show up to 7 decimals correctly for numbers < 1 if you pass an `f32` value
assert_eq!(money_f32(0.123456789),"0.123 456 7");

// we recommend you work with f64 if you're dealing with very small amounts
assert_eq!(money_f64(0.123456789),"0.123 456 789");

// up to 15 decimals correctly with f64
assert_eq!(money_f64(0.123456789012345),"0.123 456 789 012 345");

Limits

Integer part works on up to 10^14 Hundreds of trillions (Cientos de billones) when used with f64 inputs

assert_eq!(dinero_f64(123456789012345.1234) ,"123.456.789.012.345,12");

Decimal part works on up to 7 decimals when used with f32 inputs

assert_eq!(endinero::dinero_f32(0.2223334445556) ,"0,222 333 4");

For f64 if the number is less than 1, it can format up to 17 decimal places

assert_eq!(dinero_f64(0.12345678912345678) ,"0,123 456 789 123 456 78");

Note: As integer portions get larger, there might be rounding issues with the decimals
