#### 14.2.14 Numeric Input Conversions

This section describes the `scanf` conversions for reading numeric values.

The ``%d`' conversion matches an optionally signed integer in decimal radix.

The ``%i`' conversion matches an optionally signed integer in any of the formats that the C language defines for specifying an integer constant.

For example, any of the strings ``10`', ``0xa`', or ``012`' could be read in as integers under the ``%i`' conversion. Each of these specifies a number with decimal value `10`.

The ``%o`', ``%u`', and ``%x`' conversions match unsigned integers in octal, decimal, and hexadecimal radices, respectively.

The ``%X`' conversion is identical to the ``%x`' conversion. They both permit either uppercase or lowercase letters to be used as digits.

Unlike the C language `scanf`, Octave ignores the ``h`', ``l`', and ``L`' modifiers.
