scientific
Formats numeric values in scientific notation while preserving the expression's mathematical value.
scientific(value[, significantDigits]) records a scientific-notation presentation with an optional significant-digit count. The value remains exact for subsequent symbolic work.
The significant-digit count must be an integer from 1 through 1e9 and defaults to 10.
Examples
These examples use Nerdamer Notation.
Round a positive integer to three significant digits in scientific notation.
scientific(12345,3)
// → 1.23e4Preserve trailing zeros required by the requested precision.
scientific(1200,4)
// → 1.200e3Format an exact rational value with four significant digits.
scientific(1/8,4)
// → 1.250e-1Format and round a negative value.
scientific(-987654,4)
// → -9.877e5Interfaces
