Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Requires a correctly constructed control-flow graph. Counts alone do not validate graph structure or measure runtime complexity.
Example Calculation
- Directed edges: 8
- Nodes: 7
- Connected components: 1
Eight edges, seven nodes and one connected component give M=3.
Frequently asked questions
How do I use this calculator?
Enter directed edges, nodes, connected components. The result updates automatically. Use Reset to restore the example values.
What method does it use?
M=E−N+2P for a flow graph with P independent program components.. Requires a correctly constructed control-flow graph. Counts alone do not validate graph structure or measure runtime complexity.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
