val of_string : string -> num
val to_string : num -> string
Convert a number to a string, using fractional notation. Two formats are recognized: simple integer literals and a pair of integer literals separated by a '/', to indicate a rational number.
val of_float_string : string -> num
Convert a simple floating point literal to a num. Plain integer literals are also accepted; numbers written with a trailing exponent are not currently accepted.

val approx_num_exp : int -> num -> string
Approximate a number by a decimal. The first argument is the
required precision. The second argument is the number to
approximate. Num.approx_num_fix
uses decimal notation; the first
argument is the number of digits after the decimal point.
approx_num_exp
uses scientific (exponential) notation; the
first argument is the number of digits in the mantissa.
