Math.Tests.Log10 ​

Computes the base-10 logarithm of constant and time-varying inputs.

Connects a constant source with value 100 to a Log10 block and verifies that log10(100) = 2. A second Log10 block is driven by a sine wave (offset 5.5, amplitude 4.5) that stays strictly positive (1..10) as required by the logarithm domain while varying over time.
