warp.cast

warp.cast(a: Any, dtype: Any) → Any

Kernel

Reinterpret a value as a different type while preserving its bit pattern.

param a:

The value to cast

param dtype:

The target type

Example:

@wp.struct
class MyStruct:
    f: wp.float16
    i: wp.int16


@wp.kernel
def compute():
    x = wp.int32(0x40000000)
    x_casted = wp.cast(x, wp.float32)
    wp.expect_eq(x_casted, 2.0) # 0x40000000

    s = MyStruct()
    s.f = wp.float16(2.0) # 0x4000
    s.i = wp.int16(4096) # 0x1000
    s_casted = wp.cast(s, wp.int32)
    wp.expect_eq(s_casted, 0x10004000)


wp.launch(compute, dim=1)
