Need help with this div and mod stuff

[foo fighter]

Alright well this program is supposed to tell you how many bills and coins you need to make a dollar amount given by the user. Although, it only works with simple inputs like $150 and $200 and it doesn't work for something like $167.89
Could someone fix it for me.

code:

var dollar_value : real var num100, num50, num20, num10, num5, num2, num1 : real var num025, num010, num005, num001 : real color (green) put "Enter a dollar amount : $" .. color (blue) get dollar_value num100 := dollar_value div 100 num50 := dollar_value rem 50 div 50 num20 := dollar_value rem 50 div 20 num10 := dollar_value rem 20 div 10 num5 := dollar_value rem 10 div 5 num2 := dollar_value rem 5 div 2 num1 := dollar_value rem 2 div 1 num025 := dollar_value rem 1 div 0.25 num010 := dollar_value rem 0.50 div 0.10 num005 := dollar_value rem 0.25 div 0.05 num001 := dollar_value rem 0.10 div 0.01 put num100 put num50 put num20 put num10 put num5 put num2 put num1 put num025 put num010 put num005 put num001

that's because the 'div' keyword takes whatever numbers you give it, real , integer, whatever, and it casts them into ints. so just use the '/' operation in your expression.
