Math.Log

Name Mandatory Description Default Type
⬅️ Input The input float or sequence of floats to calculate the natural logarithm of. This value must be a positive number or sequence of positive numbers. FloatFloat2Float3Float4Color[Any]
Output ➡️ Outputs the natural logarithm of the input. FloatFloat2Float3Float4Color[Any]

This shard calculates the natural logarithm for the given input. The output is the exponent to which e must be raised to obtain the input value.

Details

If a sequence of floats was provided as input, the shard will calculate ln(x) for each element in the sequence and output a sequence.

If a sequence of vectors was provided as input, the shard will calculate ln(x) for each component in each vector in the sequence and output a sequence of vectors where each component in each vector is the result of the logarithmic calculation of the corresponding component in the input sequence.
