log10() : Base-10 Logarithm
On this page
Summary
Calculate the base-10 logarithm of a number.
Signature
log10(value)
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
value |
Number | Yes | The number (must be positive) |
Returns
Type: Double
The base-10 logarithm of the value.
Examples
Basic Log10
Data:
doc.Params["model"] = new {
value = 100
};
Output:
<p>log₁₀(100) = 2.000</p>
Calculate Magnitude
Data:
doc.Params["model"] = new {
value = 45000
};
Output:
<p>Order of magnitude: 10^4</p>
Decibel Calculation
Data:
doc.Params["model"] = new {
power = 100,
reference = 1
};
Output:
<p>dB: 20.0</p>
Notes
- Value must be positive (> 0)
- Returns double-precision floating-point
- Common in scientific and engineering calculations
- For natural logarithm, use
log() - log10(10) = 1, log10(100) = 2, log10(1000) = 3
