cannot convert from double to float

Question

In my database, I have a couple of "real" fields.

Heres the structure:

    database.execSQL("create table " + TABLE_LOGS + " (" 
            + COLUMN_ID + " integer primary key autoincrement," 
            + COLUMN_ID_DAY_EXERCISE + " integer not null,"
            + COLUMN_REPS + " integer not null"
            + COLUMN_WEIGHT + " real not null"
            + COLUMN_1RM + " real not null"
            + COLUMN_DATE + " integer not null"
            + ")");

Now what I am trying to do is calculate 1RM so that I can insert it into the database.

Here is my function so far:

public void createLog(long id_day_exercise, float reps, long weight) {

    // create 1rm
    // create date timestamp

    float onerm = weight/(1.0278-(.0278*reps));
    long unixTime = System.currentTimeMillis() / 1000L;
}

I am stuck here. It is giving me the error "cannot convert from double to float" for onerm. I've tried casting the weight as a float by using (Float) in front of it, I've tried using weight.floatValue() and nothing seems to work.

Answer 1

Have you tried this?

float onerm = (float) (weigth/(1.0278-(.0278*reps)));

Answer 2

What about this approach?

Float.valueOf(String.valueOf(your_double_variable));
