WebOct 9, 2013 · I'm confused when using C to cast between short and int. I assume short is 16-bit and int is 32-bit. I tested with below code: unsigned short a = 0xFFFF; signed short b = 0xFFFF; unsigned int u16tou32 = a; unsigned int s16tou32 = b; signed int u16tos32 = a; signed int s16tos32 = b; printf ("%u %u %d %d\n", u16tou32, s16tou32, u16tou32, …WebMar 30, 2024 · For a programming language VM I have been working on lately I need to create a stack for data. I have decided to use a Vec and then convert data to slices of u8.. Although turning strings into u8 is trivially easy, turning f32s and i32s into u8 slices is less obvious. If this were C I would just do a cast; however, that doesn't seem to work in …

WebMay 29, 2015 · 1 Answer. Assuming you want to convert a vector of 16 x 8 bit ints to four vectors of 4 x 32 bit ints, you can do this by first unpacking to 16 bits and then again to 32 bits: // load 8 bit vector uint8x16_t v = vld1q_u8 (p); // load vector of 16 x 8 bits ints from p // unpack to 16 bits int16x8_t vl = vreinterpretq_s16_u16 (vmovl_u8 (vget_low ...
