等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。Util.toScientificNotation()
方法的具体详情如下:
包路径:org.apache.calcite.util.Util
类名称:Util
方法名:toScientificNotation
[英]Formats a BigDecimal value to a string in scientific notation For example
1.234E-5
1.00E5
1E2
If bd
has a precision higher than 20, this method will truncate the output string to have a precision of 20 (no rounding will be done, just a truncate).
[中]例如,将BigDecimal值格式化为科学记数法中的字符串
*0.00001234的值将被格式化为1.234E-5
*100000.00的值将被格式化为1.00E5
*100(零标度)的值将被格式化为1E2
如果bd
的精度高于20,此方法将截断输出字符串,使其精度达到20(不进行舍入,只进行截断)。
