Module বিবরণ
basic যোগ, বিয়োগ, গুণ, ভাগ, গড়, clamp
advanced EMI, tax, discount, সুদ, লাভ-ক্ষতি, bill split
converter তাপমাত্রা, দূরত্ব, ওজন, BDT/USD, storage

Quick Start

from Calcly import tax, emi, discount, area_circle

# ভ্যাট হিসাব
print(tax(1000, 15))
# {'base': 1000, 'tax_rate': 15, 'tax_amount': 150.0, 'total': 1150.0}

# EMI হিসাব (৫ লক্ষ টাকা, ১২% সুদ, ২৪ মাস)
result = emi(500000, 12, 24)
print(f"মাসিক EMI: ৳{result['monthly_emi']:,.2f}")

# ছাড় হিসাব
print(discount(2000, 20))
# {'original': 2000, 'discount_percent': 20, 'discount_amount': 400.0,
#  'final_price': 1600.0, 'savings': 400.0}

# বৃত্তের ক্ষেত্রফল
print(area_circle(7))  # 153.938

Financial Examples

from Calcly import compound_interest, profit_loss, split_bill, simple_interest

# চক্রবৃদ্ধি সুদ (১ লক্ষ টাকা, ১০%, ৫ বছর, মাসিক)
ci = compound_interest(100000, 10, 5)
print(f"মোট: ৳{ci['total_amount']:,}")       # ৳164,530.88
print(f"সুদ: ৳{ci['interest_earned']:,}")    # ৳64,530.88

# লাভ-ক্ষতি
pl = profit_loss(cost_price=45000, selling_price=54000)
print(f"{pl['type']}: {pl['percent']}%")    # profit: 20.0%

# রেস্টুরেন্ট বিল ৪ জনে ভাগ (১০% tip সহ)
bill = split_bill(1200, 4, tip_pct=10)
print(f"জনপ্রতি: ৳{bill['per_person']}")    # ৳330.0

Unit Converter Examples

from Calcly import (
    celsius_to_fahrenheit, km_to_miles,
    bdt_to_usd, usd_to_bdt, kg_to_lbs, mb_to_gb
)

print(celsius_to_fahrenheit(37))     # 98.6 (জ্বর)
print(km_to_miles(100))              # 62.1371
print(bdt_to_usd(11000, rate=110))   # 100.0
print(usd_to_bdt(100, rate=110))     # 11000.0
print(kg_to_lbs(70))                 # 154.3234
print(mb_to_gb(2048))                # 2.0

Geometry Examples

from Calcly import (
    area_rectangle, area_triangle, volume_sphere,
    volume_cylinder, hypotenuse
)

room = area_rectangle(12, 8)         # 96 বর্গমিটার
triangle = area_triangle(10, 6)      # 30.0
ball = volume_sphere(5)              # 523.5988
tank = volume_cylinder(1.5, 3)       # 21.2058
c = hypotenuse(3, 4)                 # 5.0
