| The most frequently used functions are available directly from |
| the keyboard. Many of the keyboard functions also accept |
| complex numbers as arguments. |
>@,>@,>[@,>@ | Add, Subtract, Multiply, Divide. Also accepts complex |
| numbers, lists and matrices. |
| value1+ value2, etc. |
>6+,)7@ex | Natural exponential. Also accepts complex numbers. |
| e^value |
| Example |
| e^5 returns 148.413159103 |
>OQ@ | Natural logarithm. Also accepts complex numbers. |
| LN(value) |
| Example |
| LN(1) returns 0 |
>6+,)7@10x | Exponential (antilogarithm). Also accepts complex numbers. |
| 10^value |
| Example |
| 10^3 returns 1000 |
>ORJ@ | Common logarithm. Also accepts complex numbers. |
| LOG(value) |
| Example |
| LOG(100) returns 2 |
>6,1@,>&26@,>7$1@ | Sine, cosine, tangent. Inputs and outputs depend on the |
| current angle format (Degrees, Radians, or Grads). |
| SIN(value) |
| COS(value) |
| TAN(value) |
| Example |
| TAN(45) returns 1 (Degrees mode). |
