较少的数学函数是用于执行数值运算的方法，例如圆形，平方根，幂值，模数，百分比等。
Less中使用的数学函数列表：
| Index | Function | Description | Example |
|---|---|---|---|
| 1) | ceil | It is used to round up the number to next highest integer. | ceil(0.7) it round the number to:1 |
| 2) | floor | It is used to round down the number to next lowest integer. | floor(5.3) it round the number to:5 |
| 3) | percentage | It is used to transform the floating point number to percentage string. | percentage(0.5): it is equivalent to 50%. |
| 4) | round | It is used to round a floating point number. | round(4.77): it converts the number to the rounding value as:5 |
| 5) | sqrt | It is used to get the square root of a number. | sqrt(36): it defines the square root of the number as: 6 |
| 6) | abs | It is used to get the absolute value of a number. | abs(30ft): it displays the absolute value as: 30ft |
| 7) | sin | It is used to get radian on numbers. | sin(2): it calculates the sine value as: 0.90929742682 |
| 8) | asin | it is used to return arcsine (inverse of sine) of a number which returns value between -pi/2 and pi/2. | asin(1):it calculates the asin value as: 1.5707963267948966 |
| 9) | cos | It is used to get cosine of the specified value and determines radians on numbers without units. | cos(2): it calculates the cos value as: -0.4161468365471424 |
| 10) | acos | It is used to return arccosine (inverse of cosine) of a number which returns value between 0 and pi. | acos(1):it calculates the acos value as: 0 |
| 11) | tan | It is used to get tangent of the number. | tan(60): it calculates the tan value as: 0.320040389379563 |
| 12) | atan | It is used to get arctangent (inverse of tangent) of a specified number. | atan(1): it displays atan value as: 0.7853981633974483 |
| 13) | pi | It is used to get the pi value. | pi(): it determines the pi value as: 3.141592653589793 |
| 14) | pow | It is used to get the value of first argument raised to the power of second argument. | pow(3,3): it specifies the power value as: 27 |
| 15) | mod | It is used to get modulus of first argument with respect to the second argument. it also handles negative and floating point numbers. | mod(7,3): it returns the modulus value as: 1 |
| 16) | min | It is used to get the smallest value of one or more arguments. | min(70,40,55,10): it returns the minimum value as: 10 |
| 17) | max | It is used to get the highest value of one or more arguments. | max(70,40,55,10): it returns the maximum value as: 70 |
