Java去掉科学记数法

直接上代码和结果

@Test
public void scientific() {
	float a = 0.000012F;
	System.out.println(a);
	System.out.println((double) a);
	System.out.println(String.valueOf(a));
	System.out.println(Float.toString(a));
	System.out.println(new BigDecimal(a));
	System.out.println(new BigDecimal(String.valueOf(a)));
	System.out.println(new BigDecimal(Float.toString(a)));
	double b = 0.000012D;
	System.out.println(b);
	System.out.println((float) b);
	System.out.println(String.valueOf(b));
	System.out.println(Double.toString(b));
	System.out.println(new BigDecimal(b));
	System.out.println(new BigDecimal(String.valueOf(b)));
	System.out.println(new BigDecimal(Double.toString(b)));
}
