Clamp Number to Range

Clamp a finite number to inclusive lower and upper bounds.

Description

Clamp a finite number to inclusive lower and upper bounds.

Clamp a finite number to inclusive lower and upper bounds.

When to use Clamp Number to Range

Use this calculator to verify a hand calculation, normalize a value before another tool, or make the exact arithmetic convention explicit in a reproducible workflow.

Value
A finite numeric input.
Minimum
A finite numeric input.
Maximum
A finite numeric input.

How the calculation works

The formula below determines the tool output. Clamped value: The calculated clamped value.1

result = min(max(value, lower), upper) 1

Limitations and assumptions

Calculations use JavaScript number arithmetic. Binary floating-point representation can make some decimal results inexact, and values outside the supported numeric range can overflow or lose precision. Round only for presentation unless the selected rounding tool is itself the intended operation.

Alternative or Complementary approaches

Use the inverse operation to check a result when one exists: addition pairs with subtraction, multiplication with division, and powers with roots. For rounding or normalization tools, retain the unmodified value when later calculations still require full precision.
