Method Detail

createApfloat

ApfloatImpl createApfloat(java.lang.String value,
                          long precision,
                          int radix,
                          boolean isInteger)
                   throws java.lang.NumberFormatException,
                          ApfloatRuntimeException

Create a new ApfloatImpl instance from a String.

Parameters:

value - The string to be parsed to a number.

precision - The precision of the number (in digits of the radix).

radix - The radix in which the number is created.

isInteger - Specifies if the number to be parsed from the string is to be treated as an integer or not.

Returns:

A new ApfloatImpl.

Throws:

java.lang.NumberFormatException - If the number is not valid.

ApfloatRuntimeException

ApfloatRuntimeException

createApfloat

ApfloatImpl createApfloat(java.io.PushbackReader in,
                          long precision,
                          int radix,
                          boolean isInteger)
                   throws java.io.IOException,
                          java.lang.NumberFormatException,
                          ApfloatRuntimeException

Create a new ApfloatImpl instance reading from a stream.

Parameters:

in - The stream to read from.

precision - The precision of the number (in digits of the radix).

radix - The radix in which the number is created.

isInteger - Specifies if the number to be parsed from the stream is to be treated as an integer or not.

Returns:

A new ApfloatImpl.

Throws:

java.io.IOException - If an I/O error occurs accessing the stream.
