### Online Calculator and Math Help

eCalc is a free and simple to utilize logical adding machine that upholds many progressed highlights including unit change, condition fathoming, and even complex-number math. eCalc is offered as both a free online mini-computer and as a downloadable number cruncher.

### Info Mode (Algebraic versus RPN)

The online mini-computer works in either arithmetical information (default mode) or RPN input. The mini-computer mode is set by tapping on the "ALG/RPN" image in the status bar or by changing the mode inside the menu discourse box.

### Mathematical Mode

Mathematical info mode is normally alluded to as "infix documentation" and is generally utilized by most handheld adding machines. Articulations entered in logarithmic info mode are done in a way that intently looks like the common type of the articulation and the request for the activities is controlled by administrator priority and bracket.

### RPN Mode

RPN, which represents Reverse Polish documentation, is a stack-based documentation where administrators are intended to follow their operands. For instance, to assess the articulation "1 + 2" in RPN, the client is needed to enter "1 2 +" and the articulation is assessed following the administrator. Articulations that contain bracket, for example, "(1+2)*3", are assessed by taking note of the priority request and entering the structure as "1 2 + 3 *".

### Graphical Button and Keyboard Support

The online number cruncher underpins information passage through either a graphical catch or using customary PC console keys. The client is given the choice to utilize either input strategy and both are similarly legitimate; notwithstanding, there are some geometrical capacity (as noted beneath) that are restricted to PC console section just since there is a restricted measure of room accessible for graphical catch positions.

## Basic Functions

### Inverse

Multiplicative reverse (corresponding capacity) is utilized by squeezing the "1/x" catch or composing "inv()". This capacity is equivalent to x^-1 or isolating 1 by the number.

### Exponent

Numbers with types of 10 are shown with an "e", for instance 4.5e+100 or 4.5e-100. This capacity speaks to 10^x. Numbers are naturally shown in the arrangement when the number is excessively enormous or excessively little for the showcase. To enter a number in this organization utilize the example key "EEX". To do this enter the mantissa (the non example part) at that point press "EEX" or type"e" and afterward enter the type.

### Factorial

The Factorial capacity is utilized by tapping the "!" catch or type "!".

### PI

PI is a numerical consistent of the proportion of a hover's outline to its distance across.

## Online Trigonometric Functions
