exponents are accepted.

The verbs behave analogously to those of Printf.
For example, %x will scan an integer as a hexadecimal number,
and %v will scan the default representation format for the value.
The Printf verbs %p and %T and the flags # and + are not implemented,
and the verbs %e %E %f %F %g and %G are all equivalent and scan any
floating-point or complex value.
The Printf verbs %p and %T and the flags # and + are not implemented.
The verbs %e %E %f %F %g and %G are all equivalent and scan any
floating-point or complex value. For float and complex literals in
scientific notation, both the decimal (e) and binary (p) exponent
formats are supported (for example: "2.3e+7" and "4.5p-8").
Input processed by verbs is implicitly space-delimited: the
implementation of every verb except %c starts by discarding
