Example 31 with NumberFormat

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

the class NumberFormatTest method test_setCurrency.

// Test the currency symbol is correctly taken from ICU. Verifies that the fractional digits
// are not updated because DecimalFormat.setCurrency agrees not to change it.

    // The Armenian Dram is a special case where the fractional digits are 0.
    Currency amd = Currency.getInstance("AMD");
    assertEquals(0, amd.getDefaultFractionDigits());
    // Armenian Dram ISO 4217 code.

    assertEquals(2, nf.getMinimumFractionDigits());
    // currency specific fractional digits.

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

the class NumberFormatTest method test_getIntegerInstance_ar.

public void test_getIntegerInstance_ar() throws Exception {
