FLOAT Convert to 32-bit Floating Point
Section: Type Conversion Functions
Usage
Converts the argument to a 32-bit floating point number. The syntax for its use isy = float(x)
where x
is an n
-dimensional numerical array.
Conversion follows the saturation rules. Note that both
NaN
and Inf
are both preserved under type conversion.
Example
The following piece of code demonstrates several uses offloat
.
First, we convert from an integer (the argument is an integer
because no decimal is present):
--> float(200) ans = 200
In the next example, a double precision argument is passed in
--> float(400.0) ans = 400
In the next example, a complex argument is passed in.
--> float(3.0+4.0*i) ans = 3.0000 + 4.0000i
In the next example, a string argument is passed in. The string argument is converted into an integer array corresponding to the ASCII values of each character.
--> float('helo') ans = 104 101 108 111
In the last example, a cell-array is passed in. For cell-arrays and structure arrays, the result is an error.
