In first textbox i'll manually enter islamic date, at the same time on the second textbox it changes to geogorian date.

I wrote code for it, but its shows error.

import math

def intPart(floatNum):

    if floatNum < -0.0000001: return math.ceil(floatNum - 0.0000001)

    return math.floor(floatNum + 0.0000001)

def Hijri2Gregorian(yr,mth,day):

    jd1 = intPart((11 * yr + 3) / 30.0)

    jd2 = intPart((mth - 1) / 2.0)

    jd = jd1 + 354 * yr + 30 * mth - jd2 + day + 1948440 - 385

    if jd > 2299160:

    l = jd + 68569

    n = intPart((4 * l) / 146097.0)

    l = l - intPart((146097 * n + 3) / 4.0)

    i = intPart((4000 * (l + 1)) / 1461001.0)

    l = l - intPart((1461 * i) / 4.0) + 31

    j = intPart((80 * l) / 2447.0)

    d = l - intPart((2447 * j) / 80.0)

    l = intPart(j / 11.0)

    m = j + 2 - 12 * l

    y = 100 * (n - 49) + i + l

    else:

    j = jd + 1402

    k = intPart((j - 1) / 1461.0)

    l = j - 1461 * k

    n = intPart((l - 1) / 365.0) - intPart(l / 1461.0)

    i = l - 365 * n + 30

    j = intPart((80 * i) / 2447.0)

    d = i - intPart((2447 * j) / 80.0)

    i = intPart(j / 11.0)
