How to write division in c language

The division operator in C language is /, which can perform division on integers or floating-point numbers: Integer division: discard the decimal part and return an integer. Floating point division: retain the decimal part and return a floating point number. Note that dividing by 0 will result in an error, and integer division may overflow, requiring type conversion to obtain floating point results.

Division in C language

Division operation in C language is represented by / operator , can perform division on integers or floating point numbers.

Integer division

Integer division discards the decimal part and returns an integer. For example:

<code class="c">int a = 10, b = 3;
int result = a / b; // result 为 3</code>

Floating point division

Floating point division will retain the decimal part and return a floating point number. For example:

<code class="c">float a = 10.0, b = 3.0;
float result = a / b; // result 为 3.333333</code>

Notes

• Dividing by 0 Exception: Dividing by 0 will cause a runtime error, so during the division operation You should check whether the divisor is 0 before.
• Integer overflow: If the result of integer division exceeds the range of integers, integer overflow will occur.
• Type conversion: If the dividend or divisor is an integer, but you want to obtain a floating point result, you need to perform type conversion. For example:

<code class="c">int a = 10;
float b = 3.0;
float result = (float)a / b; // result 为 3.333333</code>
