| acosh() | Returns the inverse hyperbolic cosine of a number |
| asin() | Returns the arcsine of a number |
| asinh() | Returns the inverse hyperbolic sine of a number |
| atan() | Returns the arctangent of a number as a numeric value between -PI/2 and PI/2 radians |
| atan2() | Returns the angle theta of an (x,y) point as a numeric value between -PI and PI radians |
| atanh() | Returns the inverse hyperbolic tangent of a number |
| base_convert() | Converts a number from one base to another |
| bindec() | Converts a binary number to a decimal number |

| is_nan() | Returns true if a value is not a number |
| lcg_value() | Returns a pseudo random number in the range of (0,1) |
| log() | Returns the natural logarithm (base E) of a number |
| log10() | Returns the base-10 logarithm of a number |
| log1p() | Returns log(1+number) |
| max() | Returns the number with the highest value of two specified numbers |
| min() | Returns the number with the lowest value of two specified numbers |
| mt_getrandmax() | Returns the largest possible value that can be returned by mt_rand() |
| mt_rand() | Returns a random integer using Mersenne Twister algorithm |
| mt_srand() | Seeds the Mersenne Twister random number generator |
| octdec() | Converts an octal number to a decimal number |
| pi() | Returns the value of PI |
| pow() | Returns the value of x to the power of y |
| rad2deg() | Converts a radian number to a degree |
| rand() | Returns a random integer |
| round() | Rounds a number to the nearest integer |
| sin() | Returns the sine of a number |

Let’s use abs() function. see following example, where -12 converted to 12 using abs() function
<?php
$number = -12
$absnum = abs($number);
echo $absnum;
// Output : 12
?>You can do the same for other function
