 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.
