Description

getDecimal64Value

Read the specified length number of bytes from the input sequence of the specified streamBuf and load to the specified value the interpretation of those bytes as the contents octets of an encoded 64‐bit decimal value. Return 0 if successful, and a non‐zero value otherwise. The behavior is undefined unless length is non‐negative. The operation succeeds if length bytes are successfully read from the input sequence of the streamBuf without the read position becoming unavailable, and the bytes read contain a valid representation of the contents octets of an encoded 64‐bit decimal value. See the package‐level documentation of {`balber`} for the definition of the format used to encode 64‐bit decimal values.

getDoubleValue

Read the specified length number of bytes from the input sequence of the specified streamBuf and load to the specified value the interpretation of those bytes as the contents octets of a BER‐encoded real value according to the specification. Return 0 if successful, and a non‐zero value otherwise. The operation succeeds if length bytes are successfully read from the input sequence of the streamBuf without the read position becoming unavailable, and the bytes read contain a valid representation of the contents octets of a real value according to the specification.

getFloatValue

Read the specified length number of bytes from the input sequence of the specified streamBuf and load to the specified value the interpretation of those bytes as the contents octets of a BER‐encoded real value according to the specification. Return 0 if successful, and a non‐zero value otherwise. The operation succeeds if length bytes are successfully read from the input sequence of the streamBuf without the read position becoming unavailable, and the bytes read contain a valid representation of the contents octets of a real value according to the specification.

putDecimal64Value

Write the length and contents octets of the encoding of the BER encoding of the specified value to the output sequence of the specified streamBuf. Return 0 if successful, and a non‐zero value otherwise. The operation succeeds if all bytes corresponding to the length and contents octets are written to the streamBuf without the write position becoming unavailable. See the package‐level documentation of {`balber`} for the definition of the format used to encode 64‐bit decimal values.

putDoubleValue

Write the length and contents octets of the BER encoding of the specified real value (as defined in the specification) to the output sequence of the specified streamBuf. Optionally specify options, which will indicate whether ‐0.0 will be preserved or encoded as +0.0. Return 0 if successful, and a non‐zero value otherwise. The operation succeeds if all bytes corresponding to the length and contents octets are written to the streamBuf without the write position becoming unavailable.

putFloatValue

Write the length and contents octets of the BER encoding of the specified real value (as defined in the specification) to the output sequence of the specified streamBuf. Optionally specify options, which will indicate whether ‐0.0f will be preserved or encoded as +0.0f. Return 0 if successful, and a non‐zero value otherwise. The operation succeeds if all bytes corresponding to the length and contents octets are written to the streamBuf without the write position becoming unavailable.
