Expand description

The size, in bytes, of formatted values.

Required Associated Constants

Maximum number of bytes required to serialize a number to string.

Note that this value may be insufficient if digit precision control, exponent break points, or disabling exponent notation is used. If you are changing the number significant digits written, the exponent break points, or disabling scientific notation, you will need a larger buffer than the one provided. An upper limit on the buffer size can then be determined using WriteOptions::buffer_size.
