  40. def toAsciiString: String

    Converts this expression into a 7-bit safe ASCII string.

    Converts this expression into a 7-bit safe ASCII string.

    The output can be parsed using e.g. the string interpolators, and we guarantee that the expression can be perfectly reconstructed from the string output.

  41. def toRawAsciiString: String
  42. def toRawString: String
  43. def toSigRelativeString(implicit sig: BabelSignature): String

    Converts this expression into a string, taking the signature into account.

    Converts this expression into a string, taking the signature into account.

    This produces a similar output as toString, but will use the variable convention indicated by the signature. That is, if sig defines x to be a constant, then we output just x instead of the default #c(x: i).

  44. def toString(): String

    Converts this expression into a string.

    Converts this expression into a string.

    The output can be parsed using e.g. the string interpolators, and we guarantee that the expression can be perfectly reconstructed from the string output.

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.
