# tensorflow::ops::Lgamma Class Reference

Lgamma

`
#include <math_ops.h>
`


Computes the log of the absolute value of
`
Gamma(x)
`
element-wise.

## Summary


For positive numbers, this function computes log((input - 1)!) for every element in the tensor.
`
lgamma(5) = log((5-1)!) = log(4!) = log(24) = 3.1780539
`


Example:


```
x = tf.constant([0, 0.5, 1, 4.5, -4, -5.6])
tf.math.lgamma(x) ==> [inf, 0.5723649, 0., 2.4537368, inf, -4.6477685]
```

Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object

<br />


Returns:

- `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output
  ` : The y tensor.
