Floating-point float data cast to int integral type

Problem: The following code wants to get the size of a quotient between a number of two decimal types, and the results occasionally go wrong (note that occasionally)

Decima T1;

Decima T2;

int Shang =convert.toint32 (t1/t2);

WORKAROUND: You will have a rounding process when casting the decimal type data to an int integral type. As below, you need to use the Math.truncate method to take the integer digits. So it is necessary to use this method to take the whole

Problem code:

Decima T1=1.2m;

Convert.ToInt32 (T1) got 1

Decima t2=1.7m;

Convert.ToInt32 (T2) got 2

After changing to the following code:

Decima T1=1.2m;

Convert.ToInt32 (math.truncate (T1)) gets 1

Decima t2=1.7m;

Convert.ToInt32 (Math.truncate (T2)) gets 1
