Function root_io::core::parsers::parse_custom_mantissa

pub fn parse_custom_mantissa(input: &[u8], nbits: usize) -> IResult<&[u8], f32>

Some Double_* values are saved with a custom mantissa... The number of bytes can be found in the comment string of the generated YAML code (for ALICE ESD files at least). This function reconstructs a float from the exponent and mantissa
