touchgfx::CWRUtil::cosine() method

@fn static Q15 cosine(int i) Find the value of cos(i) with 15 bits precision. Find the value of cos(i) with 15 bits precision using the fact that cos(i)=sin(90- i). @see sine()

Syntax

static Q15 cosine(int i);

Arguments

i

the angle in degrees. The angle follows the angles of the clock, 0 being straight up and 90 being 3 o'clock.

Return value

the value of cos(i) with 15 bits precision on the fractional part.
