== Synopsis

Declared in `<bslx_genericinstream.h>`

getFloat32(float& variable);
----

== Description

Assign to the specified `variable` the four‐byte IEEE single‐precision floating‐point number (in host byte order) comprised of the four bytes of this stream at the current cursor location (in network byte order), update the cursor location, and return a reference to this stream. If this stream is initially invalid, this operation has no effect. If this function otherwise fails to extract a valid value, this stream is marked invalid and the value of `variable` is undefined.

== Return Value

a reference to this stream

== Parameters
