Today, the editor will share with you the relevant knowledge points about how to use BigDecimal in java. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

1. BigDecimal uses scale () to represent the number of decimal places.

BigDecimal D1 = new BigDecimal ("987.65"); BigDecimal D2 = new BigDecimal ("987.6500"); BigDecimal D3 = new BigDecimal ("98765400"); System.out.println (d1.scale ()); / / 2, representing two decimal places System.out.println (d2.scale ()); / / 4 System.out.println (d3.scale ()); / / 0

2. The stripTrailingZeros () method in BigDecimal can format BigDecimal as an equal number with zero at the end of the value.

BigDecimal D1 = new BigDecimal ("123.4500"); BigDecimal D2 = d1.stripTrailingZeros (); System.out.println (D1 + "" + d1.scale ()); / / 123.4500 4 System.out.println (D2 + "+ d2.scale ()); / / 123.45 2 because 00 BigDecimal D3 = new BigDecimal (" 1234500 "); BigDecimal D4 = d3.stripTrailingZeros (); System.out.println (D3 +"+ d3.scale ()) / / 1234500 0 System.out.println (d4 + "" + d4.scale ()); / / 1.2345E+6-2 above is all the content of this article "how to use BigDecimal in java". Thank you for reading! I believe you will gain a lot after reading this article. The editor will update different knowledge for you every day.
