How do I choose the number of decimals

Hello, is there any way to pass a value to a function and the first two decimal places only?

This in C is done like this:

printf ("%. 2fn", a);

"%.2fn" indicates that only the value followed by the first two decimal will be printed.

I want to move to a function the value and the first two decimals only.

Not sure I understood your question correctly. If you want to round the number to two decimals, use this formula:

a = int(a*100) / 100

Not sure I understood your question correctly. If you want to round the number to two decimals, use this formula:

a = int(a*100) / 100

Thanks, it works perfect.

I thought there was a native function for this.

But what is the method ?.

What should I do if I just want a decimal?

If you just want the decimal part?

a = a- int(a)

I was referring to get the value and a decimal, like this:

1.3

But I realized that you only have to use 10.

a = (a * 10) / 10

Thank you!
