Code

def p(num,num2):
   return str(num / float(num2) * 100) + "%"

p(9, 10)

9/10 = 0.9 which is 90% and that's the return of this function (string is returned)

based on the formula to calculate percentage which I have found on Google I made these two functions. while I can calculate 15% etc, how will I go about calculating 1.5 0.5 and so?

PHP Code


<?php 
def calculate(last_price, percent_buy):
    z = ('{0:.2f}'.format(float(last_price) * percent_buy))
    final = float(last_price) + float(z)
    return final

def calculate_perc(last_price, percent_buy):
    z = ('{0:.2f}'.format(float(last_price) * percent_buy))
    final = float(last_price)
    return final

def calculate_spend(main_balance, percent_buy):
    final = '${0:.2f}'.format(float(main_balance) * percent_buy)
    return final


$174.80
$22.80 


if there is a link or some better way to get the percentage in % and the quantity of the number I want to calculate please point me there, my brain hurts.
