For some reason, whenever I try to do a float calculation (with a float variable), it casts the final answer to int then right back to double. Can anyone help?

can you show the calculation ?

#

bmi = (int)(bmi*10) / 10;

#

bmi itself is already a double.

You want to cast to int or 5o double ?

#

I don't want it to cast at all.

#

Oh, shoot, I sent the wrong thing.

#

mHeight = (int)(mHeight*10) / 10;

#

Specifically, double mHeight = (int)(mHeight*10) / 10;

#

I want to round it to the tenths.

#

Shoot, should I have made the bottom number a double?

#

*denominator

Yeah so Math.round((mHeight*10)/10f)

#

Oh, right, forgot Math.round existed.

#

I'm so stupid. Thanks!
