缩放百分比计算器-针对不同数字结果的特定百分比

百分比变化 = ((目标值 - 原始值) / 原始值) * 100%

def calculate_percentage_change(original_value, target_value):
    return ((target_value - original_value) / original_value) * 100

# 示例使用
original = 100
target = 120
print(f"增长百分比: {calculate_percentage_change(original, target)}%")

original = 80
target = 60
print(f"减少百分比: {calculate_percentage_change(original, target)}%")

def calculate_percentage_change_safe(original_value, target_value):
    if original_value == 0:
        return "原始值不能为零"
    return ((target_value - original_value) / original_value) * 100

# 示例使用
original = 0
target = 50
print(f"结果: {calculate_percentage_change_safe(original, target)}")
