include vmm.inc

mov     ecx, Places      ; number of decimal places

mov     [Value], eax     ; fixed-point value
mov     [TermChar], edx  ; address of terminating character

Converts a string representing a fixed-point number into a fixed-point value. The service also returns a pointer to the character in the string that marked the end of the number. This service is only valid during initialization. Uses EAX, EDX, Flags.

• Returns the normalized value of the fixed-point number in the EAX register, and the address of the terminating character in the EDX register. The actual value is equal to EAX / (10^Places).

Places

Number of digits after the decimal point to convert. The service skips over any extra digits without calculating them into the fixed-point value.

String

Address of the null-terminated string to convert. For more information about the format of the string, see below.

A fixed-point number is a decimal number that consists of an integer, a fraction, or a combination of integer and fraction. The integer can be any combination of decimal digits and may be preceded by a plus sign (+) or a minus sign (-) to indicate a positive or negative fixed-point value. The fraction can be any combination of decimal digits but must be preceded with a decimal point (.).
