Linear Blend Calculator
Blend two numbers linearly with an interpolation factor t, where zero returns a and one returns b.
Description
Blend two numbers linearly with an interpolation factor t, where zero returns a and one returns b.
Blend two numbers linearly with an interpolation factor t, where zero returns a and one returns b.
When to use Linear Blend Calculator
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.
- Start
- Value returned when t is zero.
- End
- Value returned when t is one.
- Factor
- Interpolation factor; values outside zero to one extrapolate.
How the calculation works
The formula below determines the tool output. Blended value: The calculated blended value.1
result = a + t(b − a) 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.
