我需要一个浮点格式为n小数。
I need to format a float to "n"decimal places.
试图为BigDecimal,但返回的值是不正确的......
was trying to BigDecimal, but the return value is not correct...
public static float Redondear(float pNumero, int pCantidadDecimales) {
// the function is call with the values Redondear(625.3f, 2)
BigDecimal value = new BigDecimal(pNumero);
value = value.setScale(pCantidadDecimales, RoundingMode.HALF_EVEN); // here the value is correct (625.30)
return value.floatValue(); // but here the values is 625.3
}
我需要与小数我指定的号码返回一个浮点值。
I need to return a float value with the number of decimal places that I specify.
我需要浮动的价值回归而不是双师型。
I need "Float" value return not "Double".
在此先感谢。
您也可以传递浮点值,并使用:
You may also pass the float value, and use:
String.format("%.2f", floatValue);
