2. What is FLOPS? floating-point operations per second FLOP
measure of computer performance
kFLOPS, MFLOPS, GFLOPS, TFLOPS, PFLOPS, EFLOPS…
performance of supercomputers

3. Where is it used?
scientific calculations accuracy (FLOPS better than IPS)
kIPS, MIPS, GIPS
Fixed-point numbers – integers
Floating-point numbers – real numbers

4. Decimal → binary floating-point
−23.65 (10) =− =− (2)

5. Floating-point notation (32-bit) - IEEE-754
− =− ∙ 2 4 (2) 1 1 1 1 1 1
sign
