Hi All :wave:
So far all is going well in my little program! One thing I am stuck on however is decimal places without any rounding. Below is a screenshot of my Application Console program (as yet incomplete!) with realistic values that I will be using as input. One very important aspect of this program is the average which is shown under Calculation of Control Limits. In this instance is it presently at 0.08875...blah blah blah.
What I am interested in, is the first two numbers after the decimal place, in this case it is 08. This number is then tripled to create what we call the Cpk Division Factor. If we take 0.08 and times it by 3 we get an answer of 0.24, however, under the current circumstances, the program is multiplying the whole of the number and returning an answer of 0.266272..... and so on which gives me a discrepancy of 0.02 after the first two decimal places which is something I do not want to happen.
What I need to know is simply how to get c# to read just the first two places after the point and then multiply it. I have included my code for the program below (although it may seem messy and full of holes (something to refine later) to the experts here!)
Thanks.

}
}Thanks.
