Other information

Using this measurement code (and same for Date, Percent and Currency):

    pipe = new TranslocoDecimalPipe(service, cdr, defaultConfig.localeConfig);

    const config = { useGrouping: true, maximumFractionDigits: 3 };
    
    const start = performance.now();
    for(let i = 0; i < 100000; i++) {
      pipe.transform('123', config);
    }
    const end = performance.now();
    console.log(`Decimal Execution time: ${end - start} ms`);

Before optimization I get:

LOG: 'Decimal Execution time: 1708.9000000059605 ms'
LOG: 'Date Execution time: 7880.100000008941 ms'
LOG: 'Percent Execution time: 1741.4000000059605 ms'
LOG: 'Currency Execution time: 2233.5 ms'

After optimization I get:

LOG: 'Decimal Execution time: 35.19999998807907 ms'
LOG: 'Date Execution time: 47.599999994039536 ms'
LOG: 'Percent Execution time: 34.900000005960464 ms'
LOG: 'Currency Execution time: 38.70000000298023 ms'
