Values

Values are the basic unit of information in morpho: All functions in morpho accept values as arguments and return values.

Int

Morpho provides integers, which work as you would expect in other languages, although you rarely need to worry about the distinction between floats and integers.

Convert a floating point number to an Integer:

print Int(1.3) // expect: 1

Convert a string to an integer:

print Int("10")+1 // expect: 11

Float

Morpho provides double precision floating point numbers.

Convert a string to a floating point number:

print Float("1.2e2")+1 // expect: 121

Ceil

Returns the smallest integer larger than or equal to its argument:

print ceil(1.3) // expect: 2

Floor

Returns the largest integer smaller than or equal to its argument:

print floor(1.3) // expect: 1

Format

The format method converts a number to a String using a given format specifier:

print (1/3).format("%4.2g") // Outputs 0.33

The specifier must begin with '%' and may include:

• A minimum width, given as an integer.
• Number of decimal places to show, with '.' in front.
• A formatting option, either 'f' or 'g' where:

- 'f' displays the number in decimal form, e.g. 0.01
- 'g' uses scientific notation, e.g. 1e-2

The syntax for the formatting string is similar to that used in C and Python.
