I2CIN 0, $A1, 0, [Value] 'receive the ASCII value for "V"
I2CIN 0, $A1, 0, [DEC Value] 'receive the number 3.
I2CIN 0, $A1, 0, [HEX Value] 'receive the number $3A.
I2CIN 0, $A1, 0, [BIN Value] 'receive the number %101.
I2CIN 0, $A1, 0, [STR Value\13] 'receive the string "Value: 3A:101"
Tables 5.17 and 5.18 list all the available conversion formatters and special
formatters available to the I2CIN command. See the SERIN command for
additional information and examples of their use.

1 All numeric conversions will continue to accept new data until receiving either the specified
number of digits (ex: three digits for DEC3) or a non-numeric character.
2 To be recognized as part of a number, the minus sign (-) must immediately precede a
numeric character. The minus sign character occurring in non-numeric text is ignored and
any character (including a space) between a minus and a number causes the minus to be
ignored.
3 The hexadecimal formatters are not case-sensitive; “a” through “f” means the same as “A”
through “F”.
4 Indicated hexadecimal and binary formatters ignore all characters, even valid numerics,
until they receive the appropriate prefix ($ for hexadecimal, % for binary). The indicated
formatters can differentiate between text and hexadecimal (ex: ABC would be interpreted
by HEX as a number but IHEX would ignore it unless expressed as $ABC). Likewise, the
binary version can distinguish the decimal number 10 from the binary number %10. A
prefix occurring in non-numeric text is ignored, and any character (including a space)
between a prefix and a number causes the prefix to be ignored. Indicated, signed
formatters require that the minus sign come before the prefix, as in -$1B45.
