This is a helper program to generate frac_t static initializers, to avoid the
|
|
runtime overhead of calling frac_init during initialization.
|
|
|
|
When using the precomputed values it is possible to declare const frac_t in ROM,
|
|
which is not possible with runtime computation.
|
|
|
|
Example static configuration:
|
|
|
|
static const frac_t myfrac = {
|
|
.num = 512,
|
|
.den = 15625,
|
|
.div = { .magic = 0x8637bd05af6c69b6ull, .more = 0x0d },
|
|
};
|
|
|
|
you can use myfrac as usual:
|
|
|
|
scaled_number = frac_scale(&myfrac, unscaled_number);
