How to express the tenth power in C language

The C language has two ways to express the power of ten: the exponentiation symbol (^) and the macro (#define). Exponential operations only work with integer exponents, while macro expansion allows floating-point exponents.

Two ways to express the tenth power in C language

Power operation symbol (^)

<code class="c">pow(基数, 指数)</code>

For example: to find the 10th power of 2, you can use:

<code class="c">pow(2, 10); // 结果为 1024</code>

Macro

<code class="c">#define BASE 10
int result = BASE ^ 指数;</code>

For example: to find the 10th power of 10 Square, you can use:

<code class="c">#define BASE 10
int result = BASE ^ 10; // 结果为 10000000000</code>

Note:

• The exponentiation symbol (^) is only applicable to integer exponents .
• Replace the exponent directly with a constant during macro expansion, allows floating-point exponent.
