Sine lookup table
PostPosted: Sat Apr 26, 2008 5:38 am     Reply with quote
Regarding the sine lookup table given in the examples. I am confused how this was generated and how to get the value sine from this table.
The sine of 0 is 0 but value at subscript 0 of the table is 128 ?
How to lookup the sine of 45 for example ?

I don't know what examples you mean. But if sin(0) = 128, then perhaps the table is interpretted as unsigned numbers that are offset by 128.
