Function double_to_fix

pub extern "C" fn double_to_fix(v: f64, n: i32) -> i32

Converts an f64 to an signed fixed point integer representation where n specifies the position of the binary point in the resulting fixed point representation, e.g. f(0.5f, 16) == 0x8000. This method rounds towards -Infinity, and clamps the resulting integer to lie within the range 0x00000000 to 0xFFFFFFFF
