C# Data TypesAs explained in the variables chapter, a variable in C# must be a specified data type: Show Example
Try it Yourself » A data type specifies the size and type of variable values. It is important to use the correct data type for the corresponding variable; to avoid errors, to save time and memory, but it will also make your code more maintainable and readable. The most common data types are:
NumbersNumber types are divided into two groups: Integer types stores whole numbers, positive or negative (such as 123 or -456), without decimals. Valid types are Floating point types represents numbers with a fractional part, containing one or more decimals. Valid types are Even though there are
many numeric types in C#, the most used for numbers are Integer TypesIntThe LongThe Floating Point TypesYou should use a floating point type whenever you need a number with a decimal, such as 9.99 or 3.14515. The Use The precision of a floating point value indicates how many digits the value can have after the decimal point. The precision of Scientific NumbersA floating point number can also be a scientific number with an "e" to indicate the power of 10: Example

An integer data type is a non-decimal number between -2147483648 and 2147483647 in 32 bit systems, and between -9223372036854775808 and 9223372036854775807 in 64 bit systems. A value greater (or lower) than this, will be stored as float, because it exceeds the limit of an integer.
Does PHP have BigInt?PHP supports integer numbers with a maximum value of PHP_INT_MAX , a value defined by your processor architecture and available memory. If you need to manage integers bigger than PHP_INT_MAX , you need to use external libraries or PHP extensions such as GMP or BC Math.
How do I find the length of an integer in PHP?By using the assertion library of Webmozart Assert we can use their build-in methods to validate the input.. Use integerish() to validate that a value casts to an integer.. Use length() to validate that a string has a certain number of characters.. How do you store large numbers in JavaScript?To store large numbers in JavaScript, use BigInt() rather than + operator. If you will use the + operator, then expect loss of precision.
