Hi,

I am adding two rows which contain floating point numbers and placing them into different row

I am using following code to do that

xlWorkSheet1.Cells[i, 5] = float(Convert.ToInt32(row[13]) + Convert.ToInt32(row1[13]));

But I am getting following error:

Error1 Invalid expression term 'float'

Can anyone help me in solving this

Thanks
John

Compiler Error CS1525 means you didn't well know about casting. You can fix it by (float) instead of float. More clearly about Error CS1525, see below.

You can Try any one of the following ways as

C#

float floatValue = (float)(Convert.ToInt32(row[13]) + Convert.ToInt32(row1[13]));

(or)

C#

float floatValue1 =  float.Parse((Convert.ToInt32(row[13]) + Convert.ToInt32(row1[13])).ToString());

(or)

C#

float floatValue2 = (float)row[13] + (float)row1[13];

Solution 1

Try:

xlWorkSheet1.Cells[i, 5] = (float)(Convert.ToInt32(row[13]) + Convert.ToInt32(row1[13]));

But is there a reason why you are converting them to integer first? Wouldn't it be more obvious if you converted them to float or double values instead?
