The DM16 is the credit card sized programmer's calculator designed to display and work with numbers in hexadecimal, decimal, octal and binary, and convert numbers from one base to another. A number of specialized functions are provided to assist the programmer, including left- and right-shifting, masking, and bitwise logical operations.

The DM16 provides a wealth of functions for the programmer, including:

  • Integer and floating point math.
  • Shift functions: left and right, arithmetic and logical.
  • Rotate functions: Rotate a single position or n positions left or right, through carry or not.
  • Left justify the bits of a word.
  • Masking: Create masks to mask left or right n bits.
  • #B: return the number of bits set in a word
  • Multiply/Divide: Provides functions for multiplying single precision numbers into single precision or double precision results. Likewise, allows single or double precision dividends.
  • Bitwise Logic: and, or, not, xor
  • Bit setting and testing
  • Flag setting and testing: (user flags and overflow/carry)
