todecimal

Fractional to decimal conversion

Syntax

usddec = todecimal(quote)

usddec = todecimal(___,fracpart)

Description

usddec = todecimal(quote) returns the decimal equivalent, usddec, of a security whose price is normally quoted as a whole number and a fraction (quote).

usddec = todecimal(___,fracpart) returns the decimal equivalent, usddec, of a security whose price is normally quoted as a whole number and a fraction (quote). fracpart indicates the fractional base (denominator) with which the security is normally quoted (default = 32).

Examples

Convert Stock Quote from Fractinal to Decimal

Often secuirty prices are quoted in fractional form based on a denominator of 32. For example, if you see the quoted price is 100:05 it means 100 5/32. To find the equivalent decimal value, enter:

usddec = todecimal(100.05)

usddec = 
100.1562

You can change the defualt denominator of 32 by using the fracpart optional argument with a value of 16.

usddec = todecimal(97.04, 16)

usddec = 
97.2500
