Java java.math BigDecimal valueOf(long unscaledVal, int scale)

Description Of BigDecimal: valueOf(long unscaledVal, int scale)

The java.math.BigDecimal.valueOf(long unscaledVal, int scale) translates a long unscaled value and an int scale into a BigDecimal . This "static factory method" is provided in preference to a ( long , int ) constructor because it allows for reuse of frequently used BigDecimal values.

BigDecimal.valueOf(long unscaledVal, int scale) method returns a BigDecimal whose value is (unscaledVal ? 10^-scale).

Code Example Java BigDecimal

import java.math.BigDecimal;

public class BigDecimalExam {
 public static void main(String[] args) {
  Long d = new Long("123");

  BigDecimal bg = BigDecimal.valueOf(d, 4);

  System.out.println(bg);
 }
}
