是否有与Delphi的System.Frac等效的方法？

Question

I am looking for a method equivalent to Delphi's System.Frac in .NET.

The Delphi function strips the whole number leaving just the value after the decimal point.

I could write my own method but thought I would check?

Answer 1

I know of no such function, and I don't think it exists. Such a function would be part of the Math class, and I can't see it there. So you'll have to go with value-Math.Truncate(value) :

public static double Frac(double value)
{
  return value-Math.Truncate(value);
}

Answer 2

try this link

 double value, fraction;
 value = 8.24;
 fraction = value - (int) value;

OR

Decimal d=1.58M;
Decimal fractional=d-Decimal.Truncate(d);
