Crimson Editor – Help Topics – Built-in Calculator
Crimson Editor is equiped with a calculator that can evaluate simple expressions.
If you want to calculate a simple expression, use Crimson Editor built-in calculator to get the answer quickly.
Usage Examples
Following examples show how to use Crimson Editor built-in calculator:
Type in the expression you want to evaluate in Crimson Editor. The whole expression should be written in one line.
Press Ctrl+Enter to calculate the expression when the caret is in the line of expression.
Example:
- 3.14 * (2.43 + 0.91) <– press Ctrl+Enter when the caret is in the expression line
- = 10.487600 <– you will get the answer immediately
There are two special variables in Crimson Editor calculator:
$ans – If you want to use the value that was evaluated in the earler step, use a special variable named $ans.
$pi – The value of the variable $pi is 3.1415926535.
Example:
- $ans / $pi
- = 3.338307
Crimson Editor supports basic mathematics functions which are very similar to those used in C math library.
Example:
- sin(1.2) + atan2(3.2, 4.3)
- = 1.571809

Mathematics Functions
abs, fabs | fabs(x) - absolute value functions returns the absolute value of x, |x|. |
mod, fmod | fmod(x, y) - remainder functions returns the remainder f of the division of x by y, where f has the same sign as x, such that x=iy+f for some integer i, and |f| < |y|. |
ceil | ceil(x) - ceiling function returns the smallest integer not less than x. |
floor | floor(x) - floor function returns the largest integer not greater than x. |
round | round(x) - round function rounds its argument to the nearest integral value. |
min | min(x, y) - minimum returns the minimum of a pair of values |
max | max(x, y) - maximum returns the maximum of a pair of values |
acos | acos(x) - arccosine function returns the arccosine of x in the range 0 to pi. |
asin | asin(x) - arcsine function returns the arcsine of x in the range -pi/2 to pi/2. |
atan | atan(x) - arctangent function returns the arctangent of x in the range -pi/2 to pi/2. |
atan2 | atan2(y, x) - arctangent-and-quadrant function returns the arctangent of y/x, in the range -pi to pi, using the signs of both arguments to determine the quadrant of the return value. |
cos | cos(x) - cosine function returns the cosine of x (x specified in radians). |
sin | sin(x) - sine function returns the sine of x (x specified in radians). |
tan | tan(x) - tangent function returns the tangent of x (x specified in radians). |
cosh | cosh(x) - hyperbolic cosine function returns the hyperbolic cosine of its argument. |
sinh | sinh(x) - hyperbolic sine function returns the hyperbolic sine of its argument. |
tanh | tanh(x) - hyperbolic tangent function returns the hyperbolic tangent of its argument. |
exp | exp(x) - exponential function returns e^x. |
log | log(x) - natural logarithm function returns the natural logarithm of x. The value of x must be greater than zero. |
log10 | log10(x) - common logarithm function returns the logarithm base ten of x. The value of x must be greater than zero. |
pow | pow(x, y) - power function returns x^y. If x is negative, y must be an integer value. |
sqr | sqr(x) - square function returns x*x. |
sqrt | sqrt(x) - square root function returns the non-negative square root of x. The value of x must not be less than zero. |
