how to convert decimal points?

Question

i have value of 1.564 and 1.565 i need round this value to 1.56 and 1.56,which function suitable for this in c#.

Answer 1

do a multiply by 100 followed by a floor and followed by a divide by hundred. I am sure that there is a better way of doing it though

Math.floor(n*100)/100

Answer 2

To remove the less significant digits (1.348 -> 1.34):

Math.Floor(number * 100) / 100;

To round the number to two decimals:

Math.Round(number, 2);

To represent it as a string, for display:

number.ToString("#.00");
