Cast

Cast[val,type]

converts val to the type type, for use in compiled code.

Cast[val,type,"BitCast"]

reinterprets the bits representing val as having the type type.

Details

  • Cast is only available in compiled code.
  • Cast[val,type,"BitCast"] behaves as though val is written to memory and read back as type.
  • The input type to a bitcast must be the same length as the output type.
