Python Math

🎯 한 줄 통찰 (One-line insight)

Basic math (min/max/abs/pow) needs no import at all, but everything beyond that — sqrt, ceil, floor, pi — requires import math, marking a clear line between built-in functions and the standard math module. [S1]

🧠 핵심 개념 (Core concepts)

• Built-in, no-import functions — min(), max(), abs(), pow(x, y). [S1]
• math module — extends built-in math capability; must import math. [S1]
• math.sqrt() — square root. [S1]
• math.ceil() / math.floor() — round up / round down to nearest integer. [S1]
• math.pi — the constant π. [S1]

📖 세부 내용 (Details)

• No-import functions: min(5,10,25), max(5,10,25), abs(-7.25), pow(4,3). [S1]
• Square root: import math; x = math.sqrt(64). [S1]
• Ceil/floor: x = math.ceil(1.4) # 2; y = math.floor(1.4) # 1. [S1]
• Pi constant: x = math.pi. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — Python User Input 챕터에서 math.sqrt(float(x))처럼 사용자 입력값 계산에 재사용된다. [S1]

💻 코드 패턴 (Code patterns)

No-import vs. math-module functions (Python):

x = pow(4, 3)          # no import needed

import math
y = math.sqrt(64)
z = math.ceil(1.4)     # 2
w = math.floor(1.4)    # 1
