Mojo function
bitcast
bitcast[src_dtype: DType, src_width: Int, //, dtype: DType, width: Int = src_width](val: SIMD[src_dtype, src_width]) -> SIMD[dtype, width]
Bitcasts a SIMD value to another SIMD value.
For a discussion of byte order, see Converting data: bitcasting and byte order in the Mojo Manual.
Examples:
The following example uses bitcast to break a 32-bit integer into a vector
of four 8-bit integers:
from memory import bitcast
u32 = SIMD[DType.uint32, 1](4631)
u8x4 = bitcast[DType.uint8, 4](u32)
print(u32, u8x4) # 4631 [23, 18, 0, 0]
from memory import bitcast
u32 = SIMD[DType.uint32, 1](4631)
u8x4 = bitcast[DType.uint8, 4](u32)
print(u32, u8x4) # 4631 [23, 18, 0, 0]
Constraints:
The bitwidth of the two types must be the same.
Parameters:
- src_dtype (
DType): The source type. - src_width (
Int): The source width. - dtype (
DType): The target type. - width (
Int): The target width.
Args:
- val (
SIMD[src_dtype, src_width]): The source value.
Returns:
A new SIMD value with the specified type and width with a bitcopy of the source SIMD value.
