     Before setting new or updating existing key-value pair, free entries in nvs pages have to be available. For integer types, at least one free entry has to be available. For the string value, at least one page capable of keeping the whole string in a contiguous row of free entries has to be available. For the blob value, the size of new data has to be available in free entries.
 
-Additional data types, such as ``float`` and ``double`` might be added later.
+.. note::
+
+    The floating point types ``float`` and ``double`` are supported regardless of the FPU presence on a particular SoC.
 
 Keys are required to be unique. Assigning a new value to an existing key replaces the old value and data type with the value and data type specified by a write operation.

     在设置新的键值对或更新现有键值对之前，NVS 页中必须有可用的空闲条目。对于整数类型，至少需要有一个空闲条目。对于字符串值，至少需要一个能够将整个字符串连续存储在空闲条目中的页面。对于 blob 值，空闲条目中需要有足够空间容纳新数据的大小。
