Real32

Import can read arbitrary binary data as a sequence of single-precision numbers.
Export can convert a list of arbitrary integers or reals to binary single-precision numbers.

Import["file","Real32"] imports any file as 32-bit IEEE single-precision numbers, returning a packed array of real numbers.
Export["file",list,"Real32"] exports a list of real numbers to file.
Import["file",{"Real32",elem}] or Import["file",elem ] imports the specified element from file.
Import["file",{"Real32",{elem₁,elem₂,…}}] imports multiple elements.
See the reference pages for full general information on Import and Export.
ImportString and ExportString support the Real32 format.

	"Elements"	elements and options available in this file
	"Rules"	full rules for each element and option
	"Options"	rules for options, properties, and settings

Data representation element:
"Data" list of real numbers
By default, Import and Export use the "Data" element.
Import["file",{"Real32",n}] reads the n single-precision number from file.
Import returns Infinity for IEEE "infinity", and Indeterminate for IEEE "not‐a‐number".
Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.
