Function parse_decimal

pub fn parse_decimal<T>(
    s: &str,
    precision: u8,
    scale: i8,
) -> Result<<T as ArrowPrimitiveType>::Native, ArrowError>where
    T: DecimalType,

Expand description

Parse the string format decimal value to i128/i256 format and checking the precision and scale. Expected behavior:

The result value can’t be out of bounds.
When parsing a decimal with scale 0, all fractional digits will be discarded. The final fractional digits may be a subset or a superset of the digits after the decimal point when e-notation is used.
