Example 57 with DecimalFormat

use of java.text.DecimalFormat in project j2objc by google.

the class DecimalFormatTest method testMinimumIntegerDigits_getAndSet.

public void testMinimumIntegerDigits_getAndSet() {
    final int minIntDigit = 1;
    DecimalFormat form = (DecimalFormat) NumberFormat.getInstance(Locale.US);
    // getMaximumIntegerDigits from DecimalFormat (default to 1)
