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.
