How to use SQLite decimal precision notation -


again find myself frustrated awful sqlite documentation.

http://www.sqlite.org/datatype3.html gives example of defining decimal field decimal(10,5) doesn't explain 10 , 5 is.

i sure 10 total number of digits stored, don't know 5 means. number of digits before decimal place or after decimal place?

that page says:

in sqlite, datatype of value associated value itself, not container.

which means declared data type has no effect on values can stored in column.

the example explains decimal(10, 5) column has numeric affinity, i.e., values stored in column prefeered numbers:

> create table mytable(x decimal(10, 5)); > insert mytable values (1), ('2'), (1.23456789), ('hello'), (x'42'); > select x, typeof(x) mytable; 1           integer 2           integer 1.23456789  real hello       text b           blob

otherwise, type ignored; use use decimal(-123, 999999), or fluffy bunnies.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
