Mathematical Operations
The converters support the use of mathematical expressions as well as simple values to input data for conversion. The following is a lists of supported basic operators, advanced operators, and constants.
The following table lists basic functions built into the converters:
| Operator | Meaning | Example |
| + | addition | 12+34 |
| - | subtraction | 5.6-7.8 |
| * | multiplication | 5.5*110 |
| / | division | 128/5 |
| % | modulo (finds the remainder after division) | 14%2 |
| () | forces the expression within the parentheses to be calculated first, overriding the normal order of operations | 2*(3+4) |
The following tables list advanced functions and constants built into the converters:
| Operator | Meaning | Example |
| pow | exponentiation (raise to a power of) | pow(2,8) | sqrt | square root | sqrt(16) | sin, cos, tan | trigonometric functions (numbers are assumed to be radians) | cos(pi/3) | asin, acos, atan, atan2 | inverse trigonometric functions | acos(.5) | log | logarithm base e | log(16) | exp | e raised to a power | exp(4.1) | abs | the absolute value | abs(-5) | round | round to the nearest integer | round(1.45) | ceil | the smallest integer greater than or equal to | ceil(4.95) | floor | the greatest integer less than or equal to | floor(4.05) | max | the greater number | max(0,1,2,3,4) | min | the lesser number | min(5,6,7,8,9) |
| Constant | Meaning | Example | e | mathematical constant e, the base of natural logarithms, approximately 2.718 | e | pi | the ratio of the circumference of a circle to its diameter, approximately 3.141592653589793 | pi | ln2 | the natural logarithm of 2, approximately 0.693 | ln2 | ln10 | the natural logarithm of 10, approximately 2.302 | ln10 | log2e | the base-2 logarithm of e, approximately 1.442 | log2e | log10e | the base-10 logarithm of e, approximately 0.434 | log10e | sqrt1_2 | the square root of 0.5, or one divided by the square root of 2, approximately 0.707 | sqrt1_2 | sqrt2 | the square root of 2 | sqrt2 |
