decimalMinus(0.1, 0.2) // => -0.1
decimalMinus(1.5, 2.3) // => -1.8
decimalMinus(10.001, 20.002) // => -19.999
The current implementation only considers predictable scenarios and cannot guarantee precise calculation results under all circumstances; For calculation scenarios involving large numbers, finance, science, etc., it is recommended to use open-source libraries such as decimal.js to handle mathematical operations.
当前实现仅考虑可预期的场景，无法保证在所有情况下都能精确计算结果； 涉及到大数、金融、科学等计算场景，建议使用 decimal.js 等开源库来处理数学运算
