The java.math.BigDecimal.toPlainString() method is used to represent the current BigDecimal by which this method is called into String form without an exponent field. If the values are with a positive scale, the number of digits to the right of the decimal point is used to indicate scale. For values with a zero or negative scale, the resulting string is generated as if the value were converted to a numerically equal value with zero scale and as if all the trailing zeros of the zero scale value were present in the result.
Note: If the result of this method is passed to the string constructor, only the numerical value of this BigDecimal will be recovered, the representation of the new BigDecimal may have a different scale. In particular, this method behaves analogously to the toString method.
Syntax:
public String toPlainString()
Parameter: This method do not accepts any parameter.
Return value: This method returns the String representation of this BigDecimal number without an exponent field.
Below programs illustrates the use of toPlainString() method in java
Example 1: Example to convert BigDecimal into plain String without exponent notation
// Java program to demonstrate // toPlainString() method of BigDecimal import java.math.*; class GFG { public static void main(String[] args) { // Creating a BigDecimal object BigDecimal b; // Object of String to hold the number String input = "012345678901234567" + "8901234567890123" + "4567890123456789" + "0123456789012345" + "6789012345678901" + "2345678901234567" + "8901234567890123" + "4567890123456789" + "0123456789012345" + "6789012345678901" + "2345678901234567" + "8901234567890123" + "4567890123456789" + "0123456789012345" + "6789012345678901" + "2345678901234567" + "8901234567890123" + "4554324324362432" + "7674637264783264" + "7832678463726478" + "3264736274673864" + "7364732463546354" + "6354632564532645" + "6325463546536453" + "6546325463546534" + "6325465345326456" + "4635463263453264" + "654632498739473" ; // Converting to BigDecimal b = new BigDecimal(input); // Apply toPlainString() method String s = b.toPlainString(); // Print the result System.out.println(s); } } |
