Frequent question: Is there any limit on how large a PHP integer value can be?

PHP’s integer type has always been a 32-bit signed integer with a maximum value of 2,147,483,647.

What is the limit of PHP integer value?

PHP Integers

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.

How big can an int value be?

Is an integer PHP?

The is_int() function checks whether a variable is of type integer or not. This function returns true (1) if the variable is of type integer, otherwise it returns false.

What is the 128 bit integer limit?

The 128-bit data type can handle up to 31 significant digits (compared to 17 handled by the 64-bit long double).

Can long long int store 10 12?

This means that no, long int cannot be relied upon to store any 10 digit number.

What is the largest integer?

There is no largest positive integer. If we consider ‘n’ is the largest number of the set of integers then we will get another integer ‘n+1′ in the set Z.

How big is a long long int?

A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 bits. This doesn’t necessarily mean that a long long is wider than a long . Many platforms / ABIs use the LP64 model – where long (and pointers) are 64 bits wide.

What is the 256 bit integer limit?

The maximum value of an unsigned 256-bit integer is 2256 − 1, written in decimal as 115,​792,​089,​237,​316,​195,​423,​570,​985,​008,​687,​907,​853,​269,​984,​665,​640,​564,​039,​457,​584,​007,​913,​129,​639,​935 or approximately as 1.1579 x 1077.

What is the 16-bit integer limit?

Integer, 16 Bit: Signed Integers ranging from -32768 to +32767. Integer, 16 bit data type is used for numerical tags where variables have the potential for negative or positive values.
