另一种避免使用科学计数法的方法是使用String类的format方法,并指定格式化字符串的模式。 publicclassAvoidScientificNotationExample{publicstaticvoidmain(String[]args){doublenumber=1234567890.1234567890;StringformattedNumber=String.format("%.0f",number);System.out.println("Formatted number: "+formattedNumber);}} ...

Ifmis less than 10-3 or greater than or equal to 107, then it is represented in so-called "computerized scientific notation." Letnbe the unique integer such that 10n ≤m< 10n+1; then letabe the mathematically exact quotient ofmand 10n so that 1 ≤a< 10. The magnitude is then rep...
If the precision is less than the number of digits which would appear after the decimal point in the string returned by Float#toString(float) or Double#toString(double) respectively, then the value will be rounded using the java.math.RoundingMode#HALF_UP round half up algorithm. Otherwise, ...

sis regarded as representing an exact decimal value in the usual "computerized scientific notation" or as an exact hexadecimal value; this exact numerical value is then conceptually converted to an "infinitely precise" binary value that is then rounded to typedoubleby the usual round-to-nearest ...
The following conversions may be applied to float, Float, double and Double. 'e' '\u0065' Requires the output to be formatted using computerized scientific notation. The localization algorithm is applied. The formatting of the magnitude m depends upon its value. If m is NaN or infinite...
double number = 1234567.89; String us = String.format(Locale.US, "%,.2f", number); String france = String.format(Locale.FRANCE, "%,.2f", number); System.out.println("US: " + us); System.out.println("France: " + france);
I'm trying to format a double in scientific notation to a double not in scientific notation. Any suggestions would be greatly appreciated.
