Name:

printsingle prints a constant value as a hexadecimal single precision number

Library name:

void sollya_lib_printsingle(sollya_obj_t)

Usage:

printsingle(constant) : constant -> void

Parameters:

constant represents a constant

Description:

Prints a constant value as a hexadecimal number on 8 hexadecimal digits. The hexadecimal number represents the integer equivalent to the 32 bit memory representation of the constant considered as a single precision number.

If the constant value does not hold on a single precision number, it is first rounded to the nearest single precision number before it is displayed. A warning is displayed in this case.

Example 1:

> printsingle(3);
0x40400000

Example 2:

   > prec=100!;
   > verbosity = 1!;
   > printsingle(exp(5));
   Warning: the given expression is not a constant but an expression to evaluate. A faithful evaluation to 100 bits will be used.
   Warning: rounding up occurred before printing a value as a single.
