Math Functions
There are two types of math functions in PHP. The first type is the standard functions that operate on regular numbers. The scope and precision of these functions is limited by the operating system:
int abs(int number)
Return the absolute value of the number
double acos(double number)
Return the arc cosine of the number in radians
double asin(double number)
Return the arc sine of the number in radians
double atan(double number)
Return the arc tangent of the number in radians
double atan2(double y, double x)
Return the arc tangent of
y
/x
, with the resulting quadrant determined by the signs ofy
andx
string base_convert(string number, int frombase, int tobase)
Convert a number in a string from any base to any other base (where both bases are less than or equal to 36)
int bindec(string binary_number)
Return the decimal equivalent of the binary number
int ceil(double number)
Return the next higher integer value of the number
double cos(double number)
Return the cosine of the number in radians
string decbin(int decimal_number)
Return a string containing a binary representation of the number
string dechex(int decimal_number)
Return a string containing a hexadecimal representation of the given number
string decoct(int octal_number)
Return a string containing an octal representation of the given number
double deg2rad(double degrees)
Convert the number in degrees to the radian equivalent
double exp(double number)
Return e raised to the power of the number
int floor(double number)
Return the next ...
