Int26_6 is a signed 26.6 fixed-point number.

Format: 26 bits for integer part, 6 bits for fractional part

  • Integer range: -33554432 to 33554431
  • Fractional precision: 1/64 (0.015625)

Used for sub-pixel positioning in font rendering and graphics.

Example:

# One and a quarter: 1 + 16/64 = 1.25
value = CrImage::Math::Fixed::Int26_6[1 << 6 + 1 << 4]
puts value.to_s # => "1:16"
