Functions

half 🔒

midpoint 🔒

Computes midpoint between a and b, avoiding overflow if the sum of the high 16 bits exceeds i16::MAX.

msb_mask 🔒

Returns a bit mask for the selected bit with the most significant bit at index 0.

trunc 🔒

FreeType converts from 16.16 to 26.6 by truncation. We keep our values in 16.16 so simply zero the low 10 bits to match the precision when converting to f32.

twice 🔒
