Table 17-2: ALTFP_CONVERT Conversion Operations
Operation Features
Integer-to-Float Conversion
• Converts integers to the IEEE-754 standard floating-point
representation.
• Supports conversions of signed integers to floating-point
numbers in single, double, and single-extended precision
formats.
Float-to-Integer Conversion
• Converts IEEE-754 standard floating-point representations
to the integer-bit format.
• Supports conversions of single, double, and single-extended
precision formats to signed integers.
Float-to-Float Conversion
• Converts between IEEE-754 standard floating-point
representations.
• Supports conversions of between single double, and single-
extended precision formats.
• This operation offers the following modes:
• Single-precision format to single-extended precision
format or double-precision format.
• Double-precision format to single-precision format or
single-extended precision format.
• Single-extended precision format to single-precision or
double-precision format.
Fixed-to-Float Conversion
• Converts fixed-point format data to the IEEE-754 standard
floating-point representation.
• Supports conversions of fixed-point format data to floating-
point numbers in single, double, and single-extended
precision formats.
Float-to-Fixed Conversion
• Converts IEEE-754 standard floating-point representations
to the fixed-point format.
• Supports conversion of floating-point numbers in single,
double, and single-extended precision formats.
