Int to Decimal Conversion - Insert decimal point at specified location

Question

I have the following int 7122960
I need to convert it to 71229.60

Any ideas on how to convert the int into a decimal and insert the decimal point in the correct location?

And if you need to insert a decimal point after `n` digits, divide by `10**n` — alexis, Apr 06 '12 at 14:08

int i = 7122960;
decimal d = (decimal)i / 100;

For clarity, it might be worth using `(decimal)i / 100M` to highlight the fact that the division happens after the conversion to decimal (as it must). (As it is, the 100 is being automatically converted to decimal anyway, so it's just a clarity thing.) – Hutch Mar 18 '19 at 23:40

Simple math.

double result = ((double)number) / 100.0;

Although you may want to use decimal rather than double: decimal vs double! - Which one should I use and when?

Declare it as a decimal which uses the int variable and divide this by 100

int number = 700
decimal correctNumber = (decimal)number / 100;
