ESpecial_FP_Value (ENUM) ¶ TYPE ESpecial_FP_Value : Enumeration of special floating point values InOut: Name Initial Comment NaN 0 A (quiet) NaN PosInf 1 Positive infinity NegInf 2 Negative infinity Eps 3 Smallest positive number MaxVal 4 The maximum representable value MinVal 5 The minimum representable value

Functions ¶ Ceil (Function) CeilF (Function) Floor (Function) FloorF (Function) Truncate (Function) TruncateF (Function)

Ceil (FUN) ¶ FUNCTION Ceil : LREAL Returns the smallest integral value that is not less than f. If f is +0, -0, infinity, or NaN, then f is returned. Note This function also handles the case LREAL = REAL. InOut: Scope Name Type Input f LREAL Return Ceil LREAL

CeilF (FUN) ¶ FUNCTION CeilF : REAL Returns the smallest integral value that is not less than f. If f is +0, -0, infinity, or NaN, then f is returned. InOut: Scope Name Type Input f REAL Return CeilF REAL

Floor (FUN) ¶ FUNCTION Floor : LREAL Returns the greatest integral value that is not greater than f. if f is +0, -0, infinity, or NaN, then f is returned. Note This function also handles the case LREAL = REAL. InOut: Scope Name Type Input f LREAL Return Floor LREAL

FloorF (FUN) ¶ FUNCTION FloorF : REAL Returns the greatest integral value that is not greater than f. If f is +0, -0, infinity, or NaN, then f is returned. InOut: Scope Name Type Input f REAL Return FloorF REAL

Truncate (FUN) ¶ FUNCTION Truncate : LREAL Round to the next integral value, towards zero. if f is integral, infinity, or NaN, then f is returned. Note This function also handles the case LREAL = REAL. InOut: Scope Name Type Input f LREAL Return Truncate LREAL
