CALCULATOR
Ceiling Function Calculator
Ceiling Function. Example: Value: -2.4 number gives -2 number. Dimensionless real number, signed cases supported; no truncation-toward-zero claim. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible.
Dimensionless real number, signed cases supported; no truncation-toward-zero claim. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible. Derivation: Choose respectively greatest integer≤input or least integer≥input.
Accepted inputs: Value: -10,000 to 10,000 number.
How the calculation works
ceil(value)
Worked example
With value -2.4 number, ceiling function is -2 number.
Assumptions and limits
Dimensionless real number, signed cases supported; no truncation-toward-zero claim. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible. Derivation: Choose respectively greatest integer≤input or least integer≥input.
