Math Expressions

GridinSoft Notepad is equiped with a calculator that can evaluate simple expressions. If you want to calculate a simple expression, use GridinSoft Notepad built-in calculator to get the answer quickly.

Following examples show how to use GridinSoft Notepad built-in calculator.

1. Type in the expression you want to evaluate in GridinSoft Notepad.(The whole expression should be written in one line).
2. Select whole expression for evaluate.
3. Press Ctrl+Enter to calculate the expression. i.e.
   3.14 * (2.43 + 0.91*e) <– press Ctrl+Enter after the selected of expression
   3.14 * (2.43 + 0.91*e)=15,3974184966389 <– you will get the answer immediately in the same line

Typing the expresiion, please, take into account the next information:

• The string must be not more then 255 signs;
• You can use the spaces;
• The decimal part must be separated with a dot (not with a comma);
• The expression must be writes by usually rules of entering the expressions for computer (Example: x^2 + sin(5*y)/exp(4*z));
• GridinSoft Notepad takes into account the operations priority (in decreasing order: the function's calculation, raising to the power, multiplying and division, adding and subtraction);
• The program takes into account brackets;
• The program know the next mathematical operations:

	+ :	adding
	- :	subtraction
	* :	multiplying
	/ :	division
	^ :	raising to the power

There are two built-in variables named pi and e. The value of the variable pi=3.14159265358979. The value of the variable e=2,71828182845905. You can use this value as in example:
   pi * (2.43 + 0.91*e) <– press Ctrl+Enter when you selected the expression
   pi * (2.43 + 0.91*e)=15,4052282908561 <– you will get the answer immediately in the same line

Mathmatics Functions

---

round	round function	round(x) rounds its argument to the nearest integral value.
trunc	trunc function	trunc(x) returns the nearest smaller integer value of argument.
acos	arccosine function	acos(x) returns the arccosine of x in the range 0 to pi.
acot	arccotangent function	acot(x) returns the arccotangent of x in the range -pi/2 to pi/2.
asin	arcsine function	asin(x) returns the arcsine of x in the range -pi/2 to pi/2.
atan	arctangent function	atan(x) returns the arctangent of x in the range -pi/2 to pi/2.
cos	cosine function	cos(x) returns the cosine of x (x specified in radians).
sin	sine function	sin(x) returns the sine of x (x specified in radians).
tan	tangent function	tan(x) returns the tangent of x (x specified in radians).
cot	cotangent function	cot(x) returns the cotangent of x (x specified in radians).
cosh	hyperbolic cosine function	cosh(x) returns the hyperbolic cosine of its argument.
sinh	hyperbolic sine function	sinh(x) returns the hyperbolic sine of its argument.
tanh	hyperbolic tangent function	tanh(x) returns the hyperbolic tangent of its argument.
coth	hyperbolic cotangent function	coth(x) returns the hyperbolic cotangent of its argument.
ln	natural logarithm function	ln(x) returns the natural logarithm of x. The value of x must be greater than zero.
sqr	square function	sqr(x) returns x*x.
sqrt	square root function	sqrt(x) returns the non-negative square root of x. The value of x must not be less than zero.
