Computes the base 10 logarithm of a specified input value.
If
x
is 0,
log
is negative infinity. If
x
is not complex and is less than 0,
log
is not a number (NaN).
x
An input to this operation.
This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of numbers.
Data Type Changes on FPGA
When you add this node to a document targeted to an FPGA, this input has a default data type that uses fewer hardware resources at compile time.
log
Result of the operation.
This output assumes the same numeric representation as
x. When
x
is of the form
x
= a + bi, that is, when
x
is complex, the following equation defines
log:
Where This Node Can Run:
Desktop OS: Windows
FPGA:
DAQExpress does not support FPGA devices
Web Server: Supported in VIs that run in a web application
