计算公式

基础计算公式​

一下是计算流速流向的差值绝对值

# 绝对值
（工程后-工程前）/ 工程前*100%

计算流速的差值百分比（绝对值）​

def test(be, af):
    if not be:
        be = 0
    if not af:
        af = 0

    output = 0
    if be == af:
        output = 0
    elif be > af:
        if af == 0:
            return 0
        output = (be - af) / af * 100
    else:
        if be == 0:
            return 0
        output = (af - be) / be * 100

    return abs(output)
