SetNumberFormat

Sets the number format of a numeric entity.

Syntax

• SetNumberFormat(x, fmt)

  • x is a number, a vector, or a matrix

  • fmt is a string

Description

SetNumberFormat(x, fmt) returns x with the number format set to fmt.

fmt is one of the following values:

• "inherited"

  The global setting will be used.

• "default"

  Standard format. Very large and very small numbers are displayed in scientific (exponential) notation, and only such numbers. Insignificant zeros are not included.

• "fraction"

  Same as "default" except that rational numbers are written as the quotient of two integers instead of using decimal notation.

• "fixed"

  Numbers are written without scientific notation if at all possible and if so with a fixed number of digits after the decimal separator. Trailing zeros in the fractional part are used, if necessary, to achieve this.

• "scientific"

  All numbers are written in scientific notation with exactly one digit before the decimal separator and a fixed total number of digits. Trailing zeros are used if necessary.

Examples

L ≔ '(1/69, 16/5, 952361745213/7, 5.32E20); F ≔ '("default", "fraction", "fixed", "scientific");

ToTable(F @ (f ↦ '(f) ~ L @ (x ↦ SetNumberFormat(x\5, f))))
