# All [[3D computer graphics|3D graphics]] engines on Sony's original [[PlayStation]] and Nintendo's [[Game Boy Advance]] and [[Nintendo DS]] video game systems use fixed-point arithmetic for the same reason as Tremor and Toast: to gain throughput on an architecture without an FPU.

# [[Fractint]] represents numbers as Q3:29 fixed-point numbers[http://spanky.triumf.ca/www/fractint/periodicity.html#integer_math_anchor].

#[[VisSim]] supports a fixed-point block set to allow simulation and automatic code generation of fixed-point operations. Both word size and and radix point can be specified on an operator basis.
