Convert XNO Units

Convert between different XNO cryptocurrency units with BigInt precision. XNO uses 30 decimal places, making floating-point arithmetic unsafe. Always use this skill for accurate conversions.

Unit Reference

Conversion Factors

1 XNO    = 1,000 knano = 1,000,000 mnano = 10^30 raw
1 knano  = 1,000 mnano = 10^27 raw
1 mnano  = 10^24 raw

CLI Usage

Basic Syntax

npx xno-skills convert <amount> <from-unit> --to <to-unit>

Examples

Convert XNO to raw

npx xno-skills convert 1 XNO --to raw
# Output: 1000000000000000000000000000000

npx xno-skills convert 0.5 XNO --to raw
# Output: 500000000000000000000000000000

Convert raw to XNO

npx xno-skills convert 1000000000000000000000000000000 raw --to XNO
# Output: 1

npx xno-skills convert 500000000000000000000000000000 raw --to XNO
# Output: 0.5

Convert XNO to knano

npx xno-skills convert 1 XNO --to knano
# Output: 1000

npx xno-skills convert 0.001 XNO --to knano
# Output: 1

Convert knano to XNO

npx xno-skills convert 1000 knano --to XNO
# Output: 1

npx xno-skills convert 1 knano --to XNO
# Output: 0.001

Convert XNO to mnano

npx xno-skills convert 1 XNO --to mnano
# Output: 1000000

npx xno-skills convert 0.000001 XNO --to mnano
# Output: 1

Convert mnano to XNO

npx xno-skills convert 1000000 mnano --to XNO
# Output: 1

npx xno-skills convert 1 mnano --to XNO
# Output: 0.000001

Convert between knano and mnano

npx xno-skills convert 1000 knano --to mnano
# Output: 1000000

npx xno-skills convert 1 mnano --to knano
# Output: 0.001

Precision Handling

Why BigInt?

XNO uses 30 decimal places, which exceeds JavaScript's safe integer limit (15-17 digits). Floating-point arithmetic causes precision loss:

// WRONG - Floating point loses precision
const wrong = 0.1 + 0.2; // 0.30000000000000004

// RIGHT - BigInt maintains precision
const correct = BigInt("1000000000000000000000000000000");

Implementation Notes

1. All conversions use BigInt internally - No floating-point operations
2. Input parsing - Decimal strings converted to BigInt raw units
3. Output formatting - BigInt raw units converted to requested unit
4. No precision loss - Exact conversions for any amount

Common Precision Pitfalls

// DON'T use Number for XNO amounts
const wrong = 1.5; // Loses precision at 30 decimals

// DO use string input for CLI
// npx xno-skills convert "1.5" XNO --to raw

Common Use Cases

Wallet Balance Display

# Convert raw balance to human-readable XNO
npx xno-skills convert 500000000000000000000000000000 raw --to XNO
# Output: 0.5

# Convert to knano for smaller display
npx xno-skills convert 500000000000000000000000000000 raw --to knano
# Output: 500

Transaction Amounts

# Send 0.001 XNO
npx xno-skills convert 0.001 XNO --to raw
# Output: 1000000000000000000000000000

# Send 1 knano
npx xno-skills convert 1 knano --to raw
# Output: 1000000000000000000000000000

Fee Calculations

# Calculate fee in raw (e.g., 0.000001 XNO fee)
npx xno-skills convert 0.000001 XNO --to raw
# Output: 1000000000000000000000000

# Convert fee to mnano
npx xno-skills convert 0.000001 XNO --to mnano
# Output: 1

Large Amounts

# Convert 1 million XNO to raw
npx xno-skills convert 1000000 XNO --to raw
# Output: 1000000000000000000000000000000000000

# Convert large raw amount to XNO
npx xno-skills convert 1000000000000000000000000000000000000 raw --to XNO
# Output: 1000000

Validation

Input Validation

• Amount must be a valid number (integer or decimal)
• Unit must be one of: raw, XNO, knano, mnano
• Negative amounts are supported

Error Handling

# Invalid unit
npx xno-skills convert 1 XNO --to bitcoin
# Error: Unknown unit 'bitcoin'. Valid units: raw, XNO, knano, mnano

# Invalid amount
npx xno-skills convert abc XNO --to raw
# Error: Invalid amount 'abc'. Must be a valid number.
