将升力、支撑度和置信度四舍五入为4位小数，但升力变为1位小数

要将升力、支撑度和置信度四舍五入为特定的小数位数，可以使用编程语言中的数学函数来实现。以下是一个使用Python语言的示例代码：

def round_values(lift, support, confidence):
    rounded_lift = round(lift, 1)  # 升力保留1位小数
    rounded_support = round(support, 4)  # 支撑度保留4位小数
    rounded_confidence = round(confidence, 4)  # 置信度保留4位小数
    return rounded_lift, rounded_support, rounded_confidence

# 示例数据
lift = 12.34567
support = 0.12345678
confidence = 0.98765432

rounded_lift, rounded_support, rounded_confidence = round_values(lift, support, confidence)
print(f"Rounded Lift: {rounded_lift}")
print(f"Rounded Support: {rounded_support}")
print(f"Rounded Confidence: {rounded_confidence}")
