PHP Math functions and code samples

Mathematics ( or math ) functions are frequently used in our scripts. There are PHP math functions to take care of addition subtraction multiplication and many other mathematical requirements.

We will discuss these math functions and try to develop some sample codes on these to further understand on how to use these functions.

Function	Details
abs()	Absolute value of a number
acos()	Arc Cosine value of input
acosh()	Inverse hyperbolic cosine of input
asin()	Arc Sin value of input
asinh()	Inverse hyperbolic sine of input
atan()	Arc tangent value of input
atan2()	Arc tangent of two inputs
atanh()	Inverse hyperbolic tangent value of input
base_convert()	Convert number from one base to other
bindec()	Decimal equivalent of Binary string
ceil()	Next Higher integer after rounding
cos()	Cos value of Radian input
cosh()	Hyperbolic cosine
decbin()	Binary equivalent of Decimal number
dechex()	Hex equivalent of Decimal number
decoct()	Octal equivalent of Decimal number
deg2rad()	Convert Degree value to Radian
exp()	Value of e raised to the power of input value
expm1()	equivalent to 'exp(arg) - 1'
floor()	nearest lower integer
fmod()	reminder ( modulo ) of a division
getrandmax()	largest random value
hexdec()	Hexadecimal to decimal
hypot()	hypotenuse of a right-angle triangle
intdiv()	integer quotient of the division ( PHP 7 )
is_finite()	Checking legal finite number
is_infinite()	Checking whether value is infinite
is_nan()	Checking whether a value is not a number
lcg_value()	pseudo random number generator
log()	Log value with different Base
log10()	Log value with Base 10
log1p()	Log value with input added by 1
max()	Maximum value from array or group
min()	Minimum value from array or group
mt_getrandmax()	largest possible random value
mt_rand()	random value generator
mt_srand()	Seeds random value generator
octdec()	Convert Octal to Decimal number
PI()	Constant value PI() & M_PI
POW()	Exponential value of a Base
round()	Rounded value of a number
rand()	Random number generator
random_int()	cryptographic random integer generator ( PHP 7)
rad2deg()	Convert radian to degree
sin()	Sin value of Radian input
sinh()	Hyperbolic sine value
sqrt()	square root of number
tan()	Tangent value of Radian input
tanh()	Hyperbolic tangent value

Addition subtraction multiplication & Division

These simple scripts are easy to understand and develop. Let us try with some sample code using these basic mathematical functions. Read More

Generating Random Number

In any game or while generating passwords we use random number generators to give us random numbers. Read More

Formatting numbers

We can format numbers by specifying number of decimal places or use comma ( , ) to mark thousand places or use any other marks in our number formattingRead More

Next higher or lower number by using ceil & floor

What is the next higher number in hundredth place of 745 ? it is 800 by using ceil function. Same way 700 is the floor value of 745. Read More

Modulus or reminder of a division

We can get the modulus of two number by using modulus ( % ) function. Read More
