Quantise

v. restrict a variable to a specific set of values, form into quanta (Physics); subdivide into small but measurable units; express in terms of quantum mechanics (also quantize)

Quantization is the procedure of constraining something from a continuous set of values (such as the real numbers) to a discrete set (such as the integers). Quantization in specific domains is discussed in:Quantization (signal processing)Quantization (image processing)Quantization (sound processing)Quantization (music)Quantization (physics)Quantization (linguistics)
