numpar

A Python package for parsing human-friendly number formats into floats. Handles various number formats including comma separators, percentages, and magnitude suffixes (k, M, B).

Features

• Parse basic numbers with decimal points
• Support for comma-separated numbers (e.g., "1,234.56")
• Percentage conversion (e.g., "50%" → 0.5)
• Magnitude suffixes:
  • k/K for thousands (e.g., "1.5k" → 1500)
  • m/M for millions (e.g., "2.5M" → 2,500,000)
  • b/B for billions (e.g., "1.5B" → 1,500,000,000)
• Whitespace handling
• Combined format support (e.g., "1,234.56k")

Installation

pip install numpar

Usage

from numpar import parse_number

# Basic numbers
parse_number('123.45')      # 123.45
parse_number('-123.45')     # -123.45

# Comma separators
parse_number('1,234.56')    # 1234.56
parse_number('1,234,567')   # 1234567.0

# Percentages
parse_number('50%')         # 0.5
parse_number('12.34%')      # 0.1234

# Magnitude suffixes
parse_number('1.5k')        # 1500.0
parse_number('2.5M')        # 2500000.0
parse_number('1.5B')        # 1500000000.0

# Combined formats
parse_number('1,234.56k')   # 1234560.0
