Function rp2040_hal::rom_data::double_funcs::fix64_to_double

pub extern "C" fn fix64_to_double(v: i64, n: i32) -> f64

Converts a signed fixed point 64-bit integer representation to the nearest double value, rounding to even on tie. n specifies the position of the binary point in fixed point, so f = nearest(v/(2^n))
