Math

Returns the absolute value of $number.

Returns the arc cosine of arg in radians. acos() is the complementary function of cos(), which means that a==cos(acos(a)) for every value of a that is within acos()' range.

Returns the inverse hyperbolic cosine of $arg, i.e. the value whose hyperbolic cosine is $arg.

Returns the arc sine of $arg in radians. asin() is the complementary function of sin(), which means that a==sin(asin(a)) for every value of a that is within asin()'s range.

Returns the inverse hyperbolic sine of $arg, i.e. the value whose hyperbolic sine is $arg.

This function calculates the arc tangent of the two variables $x and $y. It is similar to calculating the arc tangent of $y / $x, except that the signs of both arguments are used to determine the quadrant of the result.

Returns the arc tangent of arg in radians. atan() is the complementary function of tan(), which means that a==tan(atan(a)) for every value of a that is within atan()'s range.

Returns the inverse hyperbolic tangent of $arg, i.e. the value whose hyperbolic tangent is $arg.

base_convert() converts a number between arbitrary bases.

Returns the decimal equivalent of the binary number represented by the $binaryString argument.

PHP ceil() function rounds fractions up.

cos() returns the cosine.

cosh() returns the hyperbolic cosine

Returns a string containing a binary representation of the given $number argument.

Returns a string containing a hexadecimal representation of the given $number argument.

Returns a string containing an octal representation of the given $number argument.

Converts the number in degrees to the radian equivalent

Calculates the exponent of e

Returns exp(number) - 1, computed in a way that is accurate even when the value of number is close to zero.

php floor() function rounds fractions down

Returns the floating point remainder (modulo) of the division of the arguments

Returns the decimal equivalent of the hexadecimal number represented by the $hexString argument.

Calculate the length of the hypotenuse of a right-angle triangle

Finds whether a value is a legal finite number

Finds whether a value is infinite

Finds whether a value is not a number

Base-10 logarithm

Returns log(1 + number), computed in a way that is accurate even when the value of number is close to zero

Natural logarithm

Find highest value

Find lowest value

Many random number generators of older libcs have dubious or unknown characteristics and are slow.

Returns the decimal equivalent of the octal number represented by the $octalString argument.

Exponential expression

Converts the radian number to the equivalent number in degrees

Generate a random integer

Rounds a float.

Returns the sine of the $arg parameter

Returns the hyperbolic sine of $arg.

Square root

tan() returns the tangent of the $arg parameter. The $arg parameter is in radians.

Returns the hyperbolic tangent of $arg, defined as sinh($arg)/cosh($arg).
