任意の正の数値の平方根を素早く求めます。
The square root is a fundamental concept in mathematics, appearing in geometry, statistics, and physics. Finding the square root of a number is the inverse operation of squaring it. While some square roots are easy to calculate mentally (like the square root of 25), most numbers result in irrational decimals. Our Square Root Calculator provides instant, high-precision results for any positive number, saving you from tedious manual estimations or long-division algorithms.
使い方
This calculator uses standard computational math libraries to provide highly accurate square root values. For perfect squares, it returns an integer. For other numbers, it provides a precise decimal expansion.
計算式
√x = r such that r² = x
Calculation Examples
1. **Perfect Square**: √144 = **12**.
2. **Irrational Number**: √2 ≈ **1.4142**.
3. **Decimal**: √0.25 = **0.5**.
